15 Hacks on How to Shrink a Swimsuit Bottom
Here are the best 15 hacks on how to shrink a swimsuit bottom:
1. Boiling Water Soak
Boiling water is a quick and easy way to shrink your swimsuit bottom.
Simply boil water and submerge your swimsuit bottom for 10-15 minutes.
The heat helps contract the fibers, making the fabric tighter. After soaking, let it air dry. If you need more shrinkage, repeat the process.
Avoid overdoing it, as excessive heat can weaken the fabric.
This method works best on nylon and spandex swimsuits but can slightly alter colors, so be mindful!
2. High-Heat Dryer Trick
Tossing your swimsuit bottom into a high-heat dryer can work wonders!
First, wash it in hot water, then place it directly in the dryer on the highest setting.
Check every 5 minutes to prevent over-shrinking. This method is great for polyester and spandex blends but can be risky for delicate fabrics.
If you notice it shrinking too much, stretch it out while it’s still warm to regain some size!
3. The Iron & Towel Press
An iron can help shrink a swimsuit’s bottom in a controlled way.
Lay the swimsuit flat, cover it with a damp towel, and gently iron it on a medium heat setting.
The combination of heat and moisture helps tighten the fabric.
Flip it over and repeat until the swimsuit bottom fits better. Be cautious with high temperatures.
4. Hair Dryer To Shrink a swimsuit bottom
If you need a quick shrink fix, grab a hairdryer! Lightly spritz your swimsuit bottom with water
Use a hairdryer on high heat, focusing on the waistband and leg openings.
Keep moving the dryer to prevent overheating.
This is ideal for last-minute fixes when you need your swimsuit bottom to fit just right before heading to the beach!

5. Sewing for a Perfect Fit
For a permanent fix, consider sewing! If your swimsuit bottom is way too loose, pin the excess fabric along the sides and sew a tight seam.
Hand stitching works fine, but using a stretch stitch on a sewing machine is best for durability.
If sewing isn’t your thing, a tailor can make quick alterations for a snug, flattering fit.
6. Hot Bathtub Soak to shrink swimsuit bottom
Want a custom fit? Try soaking your swimsuit bottom in a hot bathtub while wearing it!
The warm water makes the fabric more pliable, allowing it to mold to your body.
After soaking for 10-15 minutes, step out, towel dry, and let it air dry completely.
This method is great for slight shrinkage and gives a more personalized fit.
7. Vinegar & Hot Water Soak
A mix of hot water and white vinegar can help shrink a swimsuit bottom while preserving its elasticity.
Fill a bowl with equal parts vinegar and boiling water, then let your swimsuit sit for 10 minutes.
The vinegar tightens the fibers and removes chlorine buildup, keeping the fabric firm and snug.

It works especially well when combined with the boiling water or dryer method.
The sudden temperature change forces the fibers to contract quickly!
9. Elastic Band Hack to shrink swimsuit bottom
If your swimsuit bottom is too loose at the waist or leg openings, adding elastic bands inside the seams can work wonders.
Use a needle and thread to sew a thin elastic band into the waistline or leg cuffs to create a snugger fit.
This is an excellent hack for those who don’t want to alter the fabric permanently!
10. Steam Shrinkage Trick
Using a fabric steamer can also help shrink a swimsuit bottom.
Hold the steamer a few inches away and evenly distribute steam across the fabric.
The heat will tighten the fibers without making the swimsuit too stiff.
Let it cool down before trying it on. This method is great for delicate swimsuits that can’t handle extreme heat!
11. Hot Wash with Baking Soda
Washing your swimsuit bottom in hot water with a bit of baking soda helps tighten the fabric and remove any leftover chemicals that cause stretching.
Let it soak for 15 minutes, then rinse with cold water to lock in the shrinkage.
Baking soda also preserves the fabric’s elasticity while keeping it fresh and odor-free!
12. Layered Fabric Stitching to shrink swimsuit bottom
If your swimsuit has extra material around the waist or leg openings, folding the fabric and stitching a second seam can shrink the fit.
Use a zigzag stitch for added flexibility, ensuring the swimsuit remains comfortable and secure without compromising movement.
13. Tumble Dry with a Damp Towel
For controlled shrinking, toss your swimsuit into the dryer with a damp towel.
The moisture helps distribute heat evenly, preventing excessive shrinkage while tightening the fibers.
This is an excellent method for minor adjustments when your swimsuit has stretched out just a little.
14. Fabric Spray Shrink Method
A fabric shrink spray designed for synthetic materials can work wonders!
Lightly mist your swimsuit bottom, then use a hairdryer on low heat to tighten the fibers.
This method is gentle on delicate fabrics and great for swimsuits that can’t handle extreme heat exposure.
15. Belted Cinching Hack
If your swimsuit bottom is too loose at the waist, add a small hidden drawstring or an adjustable belt.
This allows you to control the fit without permanent alterations.
It works well for bikinis and high-waisted bottoms that tend to stretch out quickly
