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 weeks 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.

- Rated 2 out of 5 stars2 days agoMiddle part too long
I find for the large size, they made the middle part that goes between the legs too long and it makes the material bunch and ride up. But def couldn't size down anywhere else.
Emily G.Verified BuyerReviewingEssential No-Show Bikini 5-Pack - Rated 5 out of 5 stars3 days ago5 Stars
The essential no-show bikini 5-pack panties in multi colors are amazing. They are comfortable, nice colors, soft material and fills like you're not wearing any underware at all. Perfect
KarenReviewingEssential No-Show Bikini 5-Pack - Rated 5 out of 5 stars3 days agoLove these!
I bought one pair and went back to buy the 5 pack they are so good!
Kelly H.Verified BuyerReviewingPOS - Essential No-Show Bikini (ZSkus) - Rated 1 out of 5 stars3 days agoDisappointing & uncomfortable fit
I love my many other pairs of Knix undies. I have many pairs of boy cut and high cut undies in size Medium. They are comfortable and do not give me heinous panty lines. I thought I'd switch it up with the bikini style and ordered the large size (because I've read they fit small). I wear a size 6 in pants, so a large is bigger than I usually get. I assumed they'd be great, so I ordered a pack of five. Sadly, I now have 5 pairs of underwear that are too snug, give me unsightly panty lines, and are very uncomfortable. I'm at work and actually just changed out of a pair of Knix bikini undies to a pair of emergency non-Knix underwear I've kept in my purse for years. I've washed the five pairs and dried them, and unfortunately, it hasn't really helped.

Céline G.Verified BuyerReviewingEssential No-Show Bikini - Rated 5 out of 5 stars2 weeks agoPerfect fit.
Really like the essentials bikinis. Perfect.
Melanie L.Verified BuyerReviewingEssential No-Show Bikini - Rated 4 out of 5 stars3 weeks agoCute and comfy!
The only reason I give this 4 stars is because of sizing. I ordered a M, but would be more comfortable in a L. However, the Dream Boxers I got in a L and need a M. I based these purchases on the size charts. Knowing the proper sizes I need now, I would definitely order again!
Alyson N.Verified BuyerReviewingEssential No-Show Bikini - Rated 1 out of 5 stars3 weeks agoSize chart is wrong
I measured my hips according to the instructions three times (38.5"), so I figured the M (39-41") should be safe (I normally wear a size 6 and the M is supposed to fit 8-10). Wrong. They are so tight around both my thigh and my tummy that they cut in. If I'm wearing something remotely form-fitting, you can see the cut/crease lines and it is super unflattering (not to mention uncomfortable). This is so disappointing. I'm not sure what advice I can offer to others looking to buy since the information available to help make a decision is just incorrect.
