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.

How to wash
Knix underwear is 100% reusable and machine washable, just like your regular undies.
Not required. But for best results, you can rinse your leakproof with cold water in the tub or sink before washing.
Machine wash on a cold, gentle cycle with mild detergent.
For their longest life, air drying is best. Hang or lay flat to dry.
Fabric softeners, bleach, ironing, or heat from the dryer.

What our customers are saying
Generated by AI from 100 most recent customer reviews
Last updated 2 months ago
Customers say these bikini underwear are extremely comfortable and feel like wearing nothing. They appreciate the soft, stretchy material and seamless construction that eliminates panty lines under clothing. Many find them perfect for everyday wear and note they stay in place without riding up. The variety pack offers good value with attractive colors and patterns. Some mention the fit runs small initially but stretches out after a few wears. Common feedback includes praise for the no-show design under dresses and fitted clothing. A few customers note durability concerns with seams separating over time, and some find certain styles show more than expected or have sizing inconsistencies between different cuts.

Ordered same size that I have in the boy shirt.
Fits small to me
Pam M.Verified BuyerReviewingEssential No-Show Bikini 5-Pack - Last Call - Rated 4 out of 5 stars17 hours agoComfortable
I find these panties are comfortable. They are slightly tight in the beginning, but give a little as you wear. I wear size large, and extra large was too big. These panties are flattering and panty lines do not show.
KKnix17 hours agoHey Cheryl,
Thanks for the feedback! We're so glad you find them comfortable and love how flattering they are with no panty lines.

Rita A.Verified BuyerReviewingEssential No-Show Bikini - Rated 4 out of 5 stars1 week agoAlmost perfect
Comfortable. However the area that covers the bum is a smidge tight but fits everywhere else. So you can see that I am wearing underwear through tighter pants even though it's a no-show

Not sure if your sizing has changed. They don’t fit the same as the previous package that I purchased
Michelle B.Verified BuyerReviewingEssential No-Show Bikini 5-Pack - Rated 4 out of 5 stars1 month agoGreat every day underwear
I have in multiple colours and my new rose water coloured pair is definitely smaller in size compared to my other pairs. Overall the quality is great, but is not really a no-show underwear. I see underwear lines when I wear them with leggings. It’s ok with jeans.
