Reviews

6 month review

"When I first got these I was concerned about the fabrics durability, but that has not been an issue. The issue, is that the gusset is extremely narrow. I have to pull them down in the front and up in the back to have enough fabric to keep the bits inside the fabric. I have never had this issue before but a solid sneeze can dislodge a lip in these underwear."

— Sahara (3/5)

The best

"So so so so good. The most comfortable yet sexy thong ever. Crazy how the material remains so soft and stretchy whilst being cotton and never loosing the shape. This is my fav panty now, will get more for sure"

— Margherita S. (5/5)

Great the first time, loose the second

"I loved these underwear. The first order I got a size small and they were fabulous. Second order, I was post partum, so I sized up to medium. They fit when I first tried on then got loose as the day went on. So I ordered another pack of size small and same thing happened. Fit at first, but were falling off by the end of the day. I still have my original size small that work great, but the two following orders (of 6 pairs each) both stretch so much with wear I can’t wear them. I want to love these underwear again 🤪"

— Nateja (3/5)

V friendly

"Good everyday thong but definitely not no show. Can stretch out throughout the day if you are sweating though. Fabric is breathable and V friendly. Like other styles just doesn’t quite hit the mark."

— Abby V. (3/5)

Flex thong is easily the

"Flex thong is easily the most comfortable underwear I have ever owned. Stretchy but good fit, never digs in. . can act as low rise or high rise… doesn’t move around during the day!! I have it in a few colors but the summery blue is a huge vibe!!! I love that there are several matching bra styles. The fact that it’s organic cotton feels like a bonus, although for me it’s a non-negotiable. It’s just enough stretch that it’s comfortable, while still maintaining a very high proportion of organic cotton. The fit is true to size, but also feels like it will be stretchy and has enough give to grow with me in my pregnancy. I can’t recommend this model enough!!"

— Jessica W. (5/5)

comfy and cute

"cute undies that feel and look great. i got the matching bra and love feeling more put together (even if it's under my clothes)."

— camila (5/5)

"very comfortable, but a bit on the looser side. Would size down the next time"

— Julia S. (5/5)

100/100

"100/100! I’ve quit wearing thongs because they just aren’t as comfortable as I get older and have more babies…. Except these. They’re high quality, comfortable, the cut is flattering!"

— Shelby G. (5/5)
