Quick Fix: How To Make Swimsuit Bottoms Smaller Without Sewing

Yes, you can make swimsuit bottoms smaller without sewing. If you have a swimsuit bottom that is too loose, sagging, or just doesn’t fit right anymore, there are simple ways to fix it. You can tighten swimsuit bottom edges or cinch swimsuit waist areas using easy, no-sew tricks. These methods can help adjust bikini bottom size, provide a sagging swimsuit fix, or handle a swimsuit waist too loose situation without needing a needle and thread. These non-sew swimwear hacks are quick and easy ways to get a better fit right at home.

Why Swimsuit Bottoms Get Loose

Swimsuit bottoms sometimes stop fitting well. This can happen for a few reasons.

H5 Reasons for Loose Fit

Fabric Wear: Over time, swimsuit fabric can stretch out. Saltwater, chlorine, sun, and even washing can break down the elastic fibers. This makes the material less stretchy. A sagging swimsuit fix is needed when this happens.
Weight Changes: Your body changes. If you lose a little weight, your bottoms might feel loose. The swimsuit waist too loose feeling is common after weight loss.
Poor Fit From the Start: Sometimes, the size just wasn’t right when you bought it. Different brands fit differently. You might need to adjust bikini bottom size even on a new suit.
Suit Style: Some styles are just less supportive. Triangle tops and tie-side bottoms are easy to adjust. But full-coverage or banded bottoms can get loose in the waist or leg holes.

Needing to make bikini bottoms tighter is a common problem. The good news is you don’t need to be a sewing expert to fix it. Many easy DIY swimsuit fitting tricks exist.

Methods for Making Bottoms Smaller Without Sewing

There are several smart ways to make your swimsuit bottoms fit better. These methods don’t need sewing tools. They use simple items you might already have.

H4 Using Ties and Straps

Many swimsuit bottoms have ties on the sides. These are the easiest to adjust.

H5 Adjusting Existing Ties

How it works: Tie-side bikini bottoms are great for fitting. They have fabric ties at the hips.
How to do it:
- Put the bottoms on.
- Pull the ties tighter than you normally would.
- Tie a secure knot, like a double knot.
- Make sure the ties on both sides are pulled evenly. This keeps the bottoms straight.
Why it works: Pulling the ties tighter pulls the fabric towards the sides. This cinches the waist and hips. It’s a quick way to make bikini bottoms tighter right where you need it.
Pros: Very simple. Easy to change back. No damage to the suit. Great for adjusting bikini bottom size daily.
Cons: Only works on suits with ties. Can create slight gathering at the tie points. Ties might dig in if pulled too tight.

H5 Adding Ties to the Sides

If your bottoms don’t have ties, you might be able to add some. This uses the idea of using ties on swimwear. You don’t sew them on; you thread them through.

How it works: You add a simple cord or ribbon to the side seams. This acts like a drawstring.
What you need:
- A thin cord, ribbon, or fabric strip (about 1-2 feet long for each side). Choose a color that matches or looks good.
- A safety pin or bodkin (a tool for threading).
How to do it:
- Look at the side seam of your swimsuit bottom. Find a place near the top edge.
- Carefully make a small opening in the inside layer of the seam. Only cut a tiny bit, just big enough for your cord. Do this on both sides at the same height.
- Attach the safety pin to one end of your cord.
- Push the safety pin and cord through the casing (the hollow channel) of the side seam. Guide it all the way through to the other opening.
- Pull the cord through. Now you have a drawstring threaded through the side seam.
- Repeat on the other side seam if needed, or if you want ties on both sides.
- Put the bottoms on. Pull the new cords to gather the fabric along the side seam.
- Tie the cords in a bow or knot at your hip.
Why it works: Pulling the cord gathers the fabric along the seam. This makes the side panel narrower and the waist smaller. It helps make bikini bottoms tighter.
Pros: Can work on many bottom styles with thick enough side seams. Gives you adjustable sizing.
Cons: Requires making small cuts. Needs careful threading. Might not work on very thin fabric or seams. The cord might show.

H4 Adding a Drawstring or Cord to the Waist

This is a great non-sew swimwear hack for a swimsuit waist too loose. It adds a drawstring around the top edge.

H5 Adding a Waist Drawstring

How it works: You create a channel (casing) around the waist edge without sewing, then thread a cord through it.
What you need:
- A longer cord, ribbon, or elastic (enough to go around your waist plus extra for tying). Elastic works well as it stretches.
- Fabric glue (make sure it’s suitable for swimwear or stretchy fabric).
- Clips or pins to hold fabric while glue dries.
- A safety pin or bodkin.
How to do it:
- Turn your swimsuit bottoms inside out.
- Fold down the top edge of the waist by about 1/2 inch (about 1 cm).
- Use fabric glue to stick this folded edge down. Apply a thin line of glue right along the raw edge you folded under. Press it down carefully.
- Leave a small gap (about 1 inch) unglued at the back or side. This will be the opening for your drawstring.
- Use clips or pins to hold the folded fabric down while the glue dries completely. Check the glue instructions for drying time.
- Once the glue is totally dry, turn the bottoms right side out. You should have a channel or tunnel around the waist edge with one small opening.
- Attach a safety pin to one end of your cord or elastic.
- Thread the safety pin and cord through the opening you left. Push and guide it all the way around the waist channel until it comes out the same opening.
- Put the bottoms on. Pull the ends of the cord or elastic to gather the waist fabric.
- Tie the ends in a knot or bow.
Why it works: Pulling the drawstring cinches the swimsuit waist fabric, making the waist smaller. This is a good fix loose bikini bottom method.
Pros: Makes the waist much tighter. Adjustable. Can work on many bottom styles.
Cons: Requires glue (choose one safe for swim fabric). The glue line might be stiff. Creating the channel takes time and care. The drawstring adds bulk at the waist. Might not be comfortable for all-day wear or intense swimming.

H4 Using Fabric Clips or Pins

These are temporary, quick fixes. Good for a single wear or emergency.

H5 Using Swimsuit Clips

How it works: Small plastic clips designed for swimwear gather fabric.
What you need: Swimsuit clips (look for ones made for gathering straps or fabric).
How to do it:
- Identify where the bottoms are loose (sides, back, waist).
- Pinch the excess fabric together.
- Slide the swimsuit clip onto the pinched fabric to hold it in place.
- You might need one clip on each side, or one in the back waist area.
Why it works: The clip physically holds the gathered fabric, reducing the overall size of the bottom. It’s a simple way to tighten swimsuit bottom edges.
Pros: Very fast and easy. No damage to the suit. Adjustable.
Cons: Clips might be visible. Can be uncomfortable. Might slip off during activity. Not a permanent solution.

H5 Using Safety Pins

How it works: Pins gather and hold fabric, similar to clips.
What you need: Small, sturdy safety pins (stainless steel is best to avoid rust).
How to do it:
- Turn the bottoms inside out.
- Find where the fabric is loose.
- Carefully pinch the extra fabric together.
- Insert the safety pin through the pinched layers of fabric to secure the gather. Close the pin completely.
- Place pins on the inside so they don’t show. Put them where they won’t poke you. The side seams or the back waist are good spots.
Why it works: The pin holds the folded fabric, taking up the extra looseness. It’s a quick fix loose bikini bottom method.
Pros: Pins are easy to find. Very fast. Can be hidden on the inside.
Cons: Pins can poke you if not placed carefully or if they open. They can rust in water. Can snag or damage delicate fabric. Temporary fix.

H4 Strategic Bunching and Gathering

Sometimes you can just arrange the fabric differently on your body. This is a simple DIY swimsuit fitting trick.

H5 Manual Gathering Techniques

How it works: You use your hands to gather the fabric where it’s loose and arrange it to stay put.
How to do it:
- Put the bottoms on.
- If the sides are loose, push the fabric up along the ties (if it’s a tie-side) or along the side seam. This creates a ruched or bunched look.
- If the back is loose, gather the fabric slightly in the center back.
- Smooth the fabric so the gathers look intentional.
Why it works: By concentrating the fabric in certain areas, you use up the extra material. This makes the bottoms fit snugger in the loose spots. It helps make bikini bottoms tighter temporarily.
Pros: No tools needed. Can look stylish (ruching). Very fast.
Cons: Not a permanent fix. Fabric might shift back out. Works best on certain styles or fabrics that gather easily.

H4 Using Silicone Strips

This is a more advanced non-sew hack. It uses material to grip your skin.

H5 Applying Silicone Grip Tape

How it works: Silicone tape has a sticky, grippy surface. When placed inside the edges of the swimsuit, it helps hold the fabric against your skin. This stops sagging and slipping.
What you need:
- Silicone grip tape (often used in activewear waistbands or strapless bras). Look for fabric-friendly, possibly waterproof types.
- Fabric glue (the kind suitable for stretchy or swim fabric).
How to do it:
- Turn your swimsuit bottoms inside out.
- Identify the edges that are loose (e.g., the leg openings, the waist edge).
- Cut strips of silicone tape to fit along these edges.
- Apply a thin, even line of fabric glue to the back of the silicone strip.
- Carefully place the silicone strip along the inside edge of the swimsuit fabric. Position it so the grippy side will be against your skin when you wear the suit.
- Press it down firmly.
- Use clips or pins to hold the silicone in place while the glue dries completely. Check the glue instructions for drying time.
- Apply silicone to all loose edges as needed.
Why it works: The silicone creates friction against your skin. This grips the suit and prevents it from sliding down or sagging away from your body. It’s a great sagging swimsuit fix.
Pros: Can provide a very effective grip. Helps keep leg openings and waist in place. Feels more secure than pins or clips.
Cons: Requires careful application with glue. The silicone might feel strange against the skin at first. Glue must be waterproof and flexible. Not easy to remove once applied.

H4 Exploring Different Styles and Future Choices

Sometimes, the best fix is avoiding the problem next time. Knowing about swimsuit styles helps.

H5 Styles That Offer Better Fit

How it works: Some swimsuit styles are naturally more adjustable or designed to stay put.
Types to consider:
- Tie-side bottoms: As mentioned, these are highly adjustable. Easy to make bikini bottoms tighter or looser.
- Bottoms with adjustable side tabs: Some have sliders or buttons on the sides to change the width.
- High-waisted bottoms with elastic waistbands: These often have more structure and a defined waist that is less likely to stretch out quickly.
- Ruched or gathered styles: Fabric that is already gathered or ruched can hide minor fit issues and might be less prone to noticeable sagging.
- Bottoms with built-in drawstrings: Some suits come with drawstrings already in place at the waist or sides, making using ties on swimwear part of the design.
Why it works: Choosing a style with built-in adjustability means you might not need these non-sew swimwear hacks as often. They are designed for a better DIY swimsuit fitting experience from the start.
Pros: Prevents future issues. Suit looks intentional and is comfortable.
Cons: Doesn’t help with your current loose swimsuit! Requires buying a new suit.

Choosing the Right Quick Fix

Which method should you use? Think about these things:

H4 What to Consider

Your Swimsuit Style: Does it have ties? Does it have thick side seams? Is the waist a simple band?
Where is it Loose? Is it the waist (swimsuit waist too loose)? The leg holes (sagging swimsuit fix)? All over?
How Loose is it? A little loose needs a simple fix. Very loose might need more work.
How Long Do You Need the Fix? Just for one day? For the whole season?
Are You Okay with Making Changes? Some methods involve cutting a tiny bit or using glue. Others don’t change the suit at all.
What Materials Do You Have? Do you have extra cord? Fabric glue? Safety pins?

If it’s just a little loose, start with the easiest methods. Try manual gathering or safety pins first. If it’s very loose, or you want a longer-lasting fix without sewing, think about adding a drawstring or silicone tape. If you have tie-side bottoms, just adjusting the ties is the best first step to tighten swimsuit bottom edges.

Detailed Steps for Key Methods

Let’s look closer at how to do some popular non-sew swimwear hacks.

H4 Step-by-Step: Adding a Waist Drawstring (No Sew Casing)

This helps cinch swimsuit waist areas effectively.

H5 Preparing Your Suit

Turn the bottoms inside out.
Lay them flat.
Look at the top waist edge. You will fold this down to make a channel.
Decide where you want the drawstring opening. The back center is often good. Mark a spot about 1 inch wide here.

H5 Gluing the Casing

Starting next to your marked opening spot, put a thin line of fabric glue along the raw edge of the waist. Only put glue on the inside of the fabric.
Fold the fabric edge down over the glue line by about 1/2 inch. Press gently to help it stick.
Continue gluing and folding all the way around the waist, stopping when you reach the other side of your marked opening spot. Leave the 1-inch gap unglued.
Use small clips or pins to hold the folded edge down while the glue dries. Space them out every few inches.
Let the glue dry completely. This is very important. Drying time depends on the glue. It might take several hours or even a day.

H5 Threading the Drawstring

Once the glue is dry, remove all clips or pins.
Cut a piece of cord or elastic. It should be long enough to go around your waist, plus about 12 inches extra for tying.
Attach a safety pin to one end of the cord.
Thread the safety pin and cord into the opening you left in the glued channel.
Gently push the safety pin through the channel. You’ll feel it move inside the fabric tunnel.
Keep pushing and gathering the fabric onto the cord until the safety pin comes out the same opening.
Pull the cord ends to even them out.

H5 Finishing

Put the bottoms on.
Pull the drawstring ends to make the waist as tight as you need it. This helps make bikini bottoms tighter and fit your body.
Tie the ends securely in a knot or bow.
If the ends might fray, you can tie small knots at the very ends or use a tiny bit of fabric glue or clear nail polish on the tips.

This method creates a semi-permanent fix to cinch swimsuit waist areas without sewing.

H4 Step-by-Step: Adding Side Ties (Threaded Method)

This is useful for bottoms that are loose at the hips or leg openings. It helps tighten swimsuit bottom sides.

H5 Preparing the Suit

Turn the bottoms inside out.
Look at the side seam. Choose a spot near the top waist edge, or lower if the leg opening is loose.
On the inside layer of fabric along the seam, carefully make a very small cut. Just big enough for your cord to go through. Maybe about 1/4 inch. Use small, sharp scissors. Be careful not to cut the outside layer.
Make another small cut at the same height on the other side seam.
If you want ties on both sides of each hip (front and back), you’ll need a total of four small cuts per side panel, making two channels per side. Or you can thread one cord through the whole side panel seam casing if it exists. Let’s assume threading one cord through the side seam channel that might already be there, or creating one by gluing. A simpler version is just making two holes on the inside of the seam casing that is already there.

H5 Threading the Cord

Cut a piece of cord about 18-24 inches long for each side panel you are modifying.
Attach a safety pin to one end of the cord.
Insert the safety pin and cord into one of the small openings you made on the side seam.
Push the safety pin through the channel inside the seam until it comes out the other opening on the same side seam.
Pull the cord through so you have two ends hanging out of the openings on the side seam.
Repeat for the other side seam.

H5 Finishing

Turn the bottoms right side out.
Put them on.
Pull the two ends of the cord on one side to gather the fabric along that side seam. This helps make bikini bottoms tighter.
Tie the cord ends in a bow or knot.
Repeat on the other side.
You now have adjustable ties on the sides, giving you a quick way to adjust bikini bottom size.

This method uses existing seams or a simple channel creation to let you add adjustable ties, leveraging the concept of using ties on swimwear for a better fit. It’s a DIY swimsuit fitting solution that doesn’t require traditional sewing.

Tips for the Best Results

Test the Fabric: Before gluing or cutting, test a small hidden area of the fabric. Make sure the glue doesn’t damage it or show through.
Use Quality Materials: If adding cords, use something sturdy that won’t stretch too much or fall apart in water. Braided cords or swimsuit-friendly elastic are good choices.
Hide Your Work: Place pins, clips, glue lines, or openings on the inside of the suit whenever possible. This makes your non-sew swimwear hacks look cleaner.
Try It On: Always try the bottoms on as you work or after applying a fix. This helps you see how much tighter it is getting and if it’s comfortable. Adjust bikini bottom size little by little until it feels right.
Be Gentle: Swimsuit fabric is stretchy and can be delicate. Don’t pull too hard when threading cords or over-stretch the fabric when applying glue.
Consider Comfort: Some methods, like pins or thick glue lines, might be less comfortable than others. Think about how you will be moving in the suit.
Check Leg Openings: Looseness isn’t always just at the waist. Sagging swimsuit fix methods might also involve tightening leg openings. Silicone strips along the leg edges are good for this. You can also sometimes thread elastic through the leg opening casing using the same glue method as the waist.

Using these tips will help you get the best fit and make your quick fixes last longer and feel better.

Preventing Loose Swimsuit Bottoms

While these fixes are great, stopping the problem before it starts is even better.

H4 Smart Shopping and Care

Try Before You Buy: If possible, always try on swimsuit bottoms. Sizes vary a lot. Move around in the fitting room to see how they feel.
Read Reviews: Other buyers’ comments can tell you if a suit tends to stretch out or run large.
Check the Fabric Content: Look for fabric with a good amount of Spandex or Lycra (usually 15-20%). This helps the suit keep its shape.
Follow Care Instructions: Rinse your suit in cold water after every use, even if you didn’t swim. This removes chlorine, salt, and sunscreen. Hand wash gently with mild soap. Avoid wringing or twisting. Lay flat or hang to dry away from direct sun.
Rotate Your Suits: If you swim often, have a few suits. This lets each one rest and dry fully, helping the fabric recover and last longer.

Good care helps prevent the need for a sagging swimsuit fix and keeps the swimsuit waist from getting too loose too soon.

Frequently Asked Questions (FAQ)

H4 Common Questions

H5 Are these fixes permanent?
No, most non-sew methods are temporary or semi-permanent. Methods using glue or threading cords can last longer than pins or clips, but they don’t change the basic size of the fabric itself like sewing would. Fabric wear and stretch might continue over time.

H5 Will these methods damage my swimsuit?
Some methods carry a small risk. Cutting small holes for drawstrings or using glue could potentially damage delicate fabric if not done carefully or if the wrong products are used. Safety pins can snag fabric or rust. Adjusting existing ties is very low risk.

H5 Can I use these methods on any type of swimsuit bottom?
The best method depends on the suit style. Tie-sides are easiest. Bottoms with casings (like rolled edges or lined waists/legs) are good for threading cords or elastic. Very thin, unlined, or seamlessly finished edges might be harder to modify without sewing.

H5 Will the swimsuit still be comfortable after fixing it?
It depends on the method and how it’s done. Safety pins or bulky knots might be uncomfortable. A well-placed drawstring or smoothly glued silicone strip might be barely noticeable. Test the comfort level before wearing it for a long time.

H5 Can I swim in the swimsuit after making a non-sew fix?
For most methods, yes, but be aware. Pins can rust or come undone. Glue needs to be completely dry and suitable for water. Cords should be tied securely. Silicone strips are designed for getting wet. Test the fix in shallow water first if you’re unsure.

H5 Can these methods help with leg openings that are too loose?
Yes. Silicone strips are excellent for loose leg openings (a type of sagging swimsuit fix). You can also sometimes thread elastic through the leg opening casing using the same glue method described for the waist. This helps tighten swimsuit bottom leg holes.

H5 Where can I find swimsuit clips or silicone grip tape?
Check swimwear stores, fabric stores, or online retailers. Look in sections for lingerie making or activewear supplies.

These simple, non-sew swimwear hacks offer many ways to adjust bikini bottom size, tighten a swimsuit bottom, or fix a loose bikini bottom without needing any sewing skills. With a little care and the right method, you can get a much better fit from your favorite suit.
