Size and Fit Guide
How to Measure
In order to select the correct sizing, we recommend you take the following measurements using a soft tape measure. If necessary, ask someone else to help.
Waist
Measure around the narrowest part of your torso, usually just above your belly button. Keep the tape snug and level, but not tight. The number where it meets is your waist measurement.
Hip
Stand with your feet together and measure around the fullest part of your hips and buttocks. Keep the tape level and snug, but not tight. The number where it meets is your hip measurement.

Leakproof swim works in layers
The 3-layer liner absorbs and locks in leaks, whether you're in or out of the water. When washed with detergent, blood releases through the top layer for a fresh, clean suit.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 3 days ago
Customers say these swim bottoms are comfortable and provide good coverage, with many praising the flattering fit and soft fabric. Users report feeling confident wearing them during their period, noting the thin gusset doesn't feel bulky like other brands. Many mention they work well for hours without leaks and appreciate the peace of mind they provide. Common sizing feedback suggests ordering a size up, as they tend to run small. Some customers note the absorbent layer fills with water when swimming, requiring squeezing out when exiting pools. While most find them effective, a few experienced leaks on heavier days or with worn pairs showing damage marks.

True to size and comfortable!
Angela C.Verified BuyerReviewingLeakproof Bikini Swim Bottom - Rated 5 out of 5 stars1 month agoComfortable and beautiful
If you want comfortable and beautiful swimsuit, this is your swimsuit.
Sheila H.Verified BuyerReviewingLeakproof Sculpt Bikini Swim Bottom - Rated 3 out of 5 stars3 months agoNot as high
I just automatically assumed this would be the same bottoms as I bought before, but I find them slightly lower. Going to need to work on my midsection a little before feeling comfortable in them.
I rated the ease of use and effectiveness low since I haven’t worn them yet. Just tried them on. These requests come too early for me.

So cute
EleniReviewingLeakproof Bikini Swim Bottom - Rated 5 out of 5 stars8 months agoSuper thin
I used them for the first time on a camping trip when i unfortunately got my period but these were amazing. I’ve tried other leakproof swim from other brands but the gusset was so thick and felt like a diaper, whereas the knix one is super thin the crotch, feel like a regular swim bottom. Didn’t use a tampon with it either and I could wear them for hours. I might’ve wanted an XS instead of S but S still works

Chantal L.Verified BuyerReviewingLeakproof Bikini Swim Bottom - Rated 5 out of 5 stars9 months agoLeakproof swim bottom
Amazing product! Minimal swell in water and very discrete, all while being effective. I would recommend ordering a size up for a comfortable fit.
Peachie B.Verified BuyerReviewingLeakproof Bikini Swim Bottom - Rated 3 out of 5 stars9 months agoFit small
These are good quality but fit small; bought them on sale so they’re final sale :(
I had bought based on my daughter’s exact measurements, so would recommend sizing up.
