Waist

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.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 5 months ago
Customers say these underwear are incredibly comfortable and feel like wearing nothing at all. Many appreciate the soft, butter-like fabric and no-show design that works well under tight clothing without visible panty lines. Users find them effective for light protection during periods, spotting, or minor bladder leaks, with many praising the confidence they provide for daily wear. Common feedback includes that they run small, with several reviewers recommending sizing up for better fit. Some mention the absorbent area could extend higher in the front for better coverage. While most love the comfort and functionality, a few note issues with side leakage or fabric breathability.

- Rated 5 out of 5 stars4 minutes agoI was won over.
I've heard of period underwear but was skeptical that they would be effective. I went with a light leakproof version to handle sweat and the daily vaginal discharge and I was pleasantly surprised of the comfort and absorbency. Will definitely order more pairs and see if they can handle period protection.

I can't say enough good things about these. They fit perfectly and are perfect for light days or for added protection with tampons. I finally have peace of mind when my period comes now. They are truly no-show and very comfortable.

I haven’t gotten a chance to use them yet but can already tell they’re better quality than other brands. Will update after use.
MPMegan P.Verified BuyerReviewingLight Leakproof No-Show Bikini - Rated 5 out of 5 stars6 days agoFinally feel dry
Even wearing cotton underwear, I never felt dry. I bought a pack of these to just try them out. Now I am getting a few more packs

RGregina g.Verified BuyerReviewingLight Leakproof No-Show Bikini* - Rated 2 out of 5 stars1 week agoNot the style for me
This style is super low cut, and just not the fit I was looking for. If this wasn't a last call item I would have returned
TDTerry D.Verified BuyerReviewingLight Leakproof No-Show Bikini - Last Call - Rated 5 out of 5 stars2 weeks agoI never go a day without my Knix!
As with every pair of Knix I own, these are so comfortable and keep me feeling protected all day from light bladder leaks. They have enough stretch to still be comfy on the days I feel bloated, and making me feel safe if I start to spot before my period is expected to arrive.
