Period Swimwear Size Guide: Finding Your Perfect Fit

Finding the right size in period swimwear is crucial for both comfort and confidence. Unlike regular swimwear, period swimwear needs to fit snugly to provide optimal protection while still allowing freedom of movement. This comprehensive sizing guide will help you choose the perfect fit for leak-free swimming.

Why Proper Sizing Matters for Period Swimwear

Period swimwear has built-in absorbent layers that need to sit close to your body to create an effective seal. Getting the right fit ensures:

Maximum leak protection
Comfortable all-day wear
Confidence in the water
Proper absorption capacity

How to Choose Your Size for Period Swimwear

We recommend choosing your normal underwear size, or size up if you are between sizes; eg if size 12-14, select a 14. If you are tall we also recommend sizing up for our 1 pieces.

Period Swimwear Fit Tips

Snug but not tight: Period swimwear should feel secure without cutting in
Check the leg openings: They should lay flat against your skin
Test the waistband: It shouldn't roll or dig in
Consider your flow: Our period swimwear is suited for light to moderate flow days

What to Do If You're Between Sizes

If your measurements fall between two sizes:

For bikini briefs: Size up for comfort, especially if you have a heavier flow
For one-pieces: Consider your torso length - longer torsos may need to size up
For teens: Remember that growing bodies change quickly - consider sizing up if between sizes or if your teen is tall.

Care Instructions for Optimal Fit

Proper care maintains the fit and effectiveness of your period swimwear:

Rinse immediately after use
Wash in cold water with mild detergent
Air dry only - heat can damage the absorbent layers
Avoid fabric softeners which can reduce absorption
