How to Tighten Bathing Suit Leg Openings: A Comprehensive Guide

Whether you’ve recently lost weight, purchased a new bathing suit, or found your favorite swimsuit has become a bit loose over time, you may encounter the need to tighten the leg openings of your swimsuit. Ensuring a snug and secure fit is crucial for comfort and confidence while enjoying the water. In this comprehensive guide, we’ll explore various methods to tighten bathing suit leg openings, allowing you to make the most of your swimwear.

Why Tighten Bathing Suit Leg Openings

Before delving into the methods, let’s understand the importance of having well-fitting leg openings for your bathing suit:


A properly fitting bathing suit prevents discomfort and chafing caused by loose leg openings that move around as you swim or walk.


A snug fit enhances your confidence, ensuring that your swimsuit stays in place, regardless of your activity.

Preventing Wardrobe Malfunctions:

Tightening the leg openings helps avoid embarrassing situations, such as accidental exposure, which can occur with loose-fitting swimsuits.

Step 1: Measure and Assess

Before taking any actions, measure your body and evaluate the fit of your bathing suit. Identify the areas where the leg openings need adjustment. Consider factors such as the type of swimsuit (one-piece or two-piece), the material, and the elasticity of the fabric.

Step 2: Sewing Adjustments

2.1. Using a Sewing Machine

If you have basic sewing skills, a sewing machine can be a powerful tool for tightening leg openings. Here’s how:

  • Turn your swimsuit inside out.
  • Using a zigzag stitch, sew along the inner edge of the leg openings, ensuring you don’t stretch the fabric too much while sewing.
  • Try on the swimsuit after sewing to check the fit. If it’s still too loose, you can sew another row of stitches closer to the fabric edge.

2.2. Hand Sewing

If you prefer hand sewing or don’t have access to a sewing machine, you can make adjustments using a needle and thread:

  • Turn your swimsuit inside out.
  • Thread a needle with a matching thread color.
  • Create small, evenly spaced stitches along the inner edge of the leg openings.
  • Tie knots at the ends of your stitching to secure the thread.
  • Try on the swimsuit and make further adjustments if needed.

Step 3: Elastic Inserts

Another effective method to tighten leg openings is by adding elastic inserts. Here’s how:

  • Turn your swimsuit inside out.
  • Measure and cut a piece of elastic that matches the length of the leg opening you want to adjust.
  • Sew the ends of the elastic to the inner edge of the leg openings, ensuring the elastic is evenly distributed along the opening.
  • Try on the swimsuit to ensure the fit is comfortable.

Step 4: Use Drawstrings

If your swimsuit has drawstrings, take advantage of them to adjust the leg openings. Here’s how:

  • Pull the drawstrings to tighten the leg openings to your desired fit.
  • Tie knots at the ends of the drawstrings to secure the adjustment.
  • Trim any excess drawstring length, and your leg openings are tightened.

Step 5: Safety Pins or Clips

For a quick and temporary fix, use safety pins or clips to tighten the leg openings. Keep in mind that this method is less durable and may not be suitable for extensive water activities. Here’s how:

  • Fold the edge of the leg openings to the desired tightness.
  • Use safety pins or clips to secure the folded fabric.
  • Be cautious to avoid pricking yourself while wearing the swimsuit.

Step 6: Professional Alterations

If you’re uncomfortable making alterations yourself or if your swimsuit is particularly expensive or intricate, consider taking it to a professional tailor or alterations specialist. They can assess your swimsuit and make precise adjustments to ensure a perfect fit.

Maintenance Tips

To maintain the integrity of your tightened leg openings, follow these tips:

  • Hand wash your swimsuit after each use, using a gentle detergent.
  • Rinse the suit thoroughly to remove chlorine or saltwater.
  • Avoid wringing out the suit to prevent stretching.
  • Allow it to air dry, preferably flat, to maintain the fabric’s elasticity.


Tightening the leg openings of your bathing suit is a valuable skill, ensuring that you can enjoy the water with comfort and confidence. Whether you choose to sew, use elastic inserts, drawstrings, safety pins, or seek professional alterations, the key is to ensure a snug and secure fit that complements your body shape. By following the steps and maintenance tips outlined in this guide, you can extend the life of your swimsuit and make the most of your time in the water.

Ensuring a Perfect Fit

In addition to tightening the leg openings, here are some additional tips to ensure your swimsuit fits perfectly:

Proper Sizing:

When purchasing a new swimsuit, pay attention to the sizing chart provided by the manufacturer. Sizing can vary between brands, so it’s essential to select the right size for your body shape.

Try Before You Buy:

If possible, try on swimsuits in-store before making a purchase. This allows you to assess the fit, comfort, and style. It’s an excellent way to avoid returns and exchanges.

Consider Adjustable Styles:

Some swimsuits come with adjustable features like tie-backs, adjustable straps, or removable padding. These can be beneficial for achieving a customized fit.

Body Shape Awareness:

Recognize your body shape and choose swimsuits that flatter your figure. For example, high-waisted bottoms can elongate the legs, while halter tops can provide extra support.

Mix and Match:

If you’re wearing a two-piece swimsuit, consider mixing and matching top and bottom sizes to achieve the perfect fit for each part of your body.

Tailor-Made Swimsuits:

If you have specific fitting requirements that are challenging to find in ready-made swimsuits, you can explore custom or tailor-made options. These suits are designed to your precise measurements.

Stay Hydrated:

Swimsuit fabrics can sometimes stretch when wet. To ensure a secure fit when in the water, consider sizing down slightly, knowing that the fabric may expand when it gets wet.

Keeping Your Swimsuit in Great Condition

Maintaining your swimsuit’s fit and appearance is essential for long-lasting enjoyment. Here are some tips for keeping your swimsuit in great condition:

  • Rinse your swimsuit immediately after swimming in chlorinated pools or saltwater to prevent damage.
  • Hand wash your swimsuit with a gentle detergent and cold water to preserve the fabric and colors.
  • Avoid wringing out the swimsuit, as this can lead to stretching. Instead, gently press the water out.
  • Allow your swimsuit to air dry, preferably laid flat, to prevent stretching and distortion from hanging.
  • Store your swimsuit in a cool, dry place away from direct sunlight, which can cause fading.

By following these additional tips, you can ensure that your swimsuit remains in excellent condition and maintains its perfect fit for many seasons of enjoyable water activities. Whether you’re hitting the beach, lounging by the pool, or enjoying water sports, a well-fitting swimsuit is your ticket to comfort and confidence.
