I love this style so much - it fits perfectly! The owner advised me because of the give/stretch to maybe size down (or at least stay true to size). I sized down from Large to Medium and they are a PERFECT FIT! The most comfortable undewear I've worn in a long time! Would highly recommend.

I really liked an underwear brand I used to buy, but then they started different materials so I decided to try Iteration. These are so much better! They fit perfectly, they feel like I'm wearing nothing, and they look way cuter than any other comfortable underwear I've ever worn. I will definitely be buying more pairs.
- MMMegan M.Verified BuyerReviewingLow-Rise Bikini | Pink SandI recommend this productRated 5 out of 5 starsIncredibly comfy!
Hands down the most comfortable low-rise bikini underwear I’ve ever owned. Perfect fit, smooth silhouette, and zero riding up throughout the day. They hit at the perfect spot on the hips and feel super high quality. Huge shout-out for the sustainable packaging, too! Cannot wait to order a pair of these in the new blue color.

These were clearly designed with comfort in mind, I have one in every colour and it makes me happy every time I get to pull one out of my undies drawer!
IiterationMar 3, 2025It makes us SO happy knowing our undies bring you joy every time you reach for them - that's exactly what we hoped for when we designed them, making comfort as our top priority. Your enthusiasm and support means the world to us!! 💜
- SPSally P.Verified BuyerReviewingLow-Rise Bikini | OnyxI recommend this productAge Range 45-54Size Purchased MRated 5 out of 5 starsMost comfortable underwear, ever.
After losing some weight, I needed a whole new everyday underwear wardrobe, and I bought almost all of it at Iteration, in several colors. The bikini-style cut is so flattering, with the center dip and pleat, but it offers the right amount of coverage. The material is so soft and breathable and non-restrictive, without becoming baggy or loose. They wash beautifully. They check all the boxes for me.
