Reviews

Great overall

"Super cute and overall very comfortable underwear! My only issue is that they can be a little loose if I’m not wearing tight fitting bottoms, like leggings or skinny jeans. I don’t like the feel of my underwear shimmying around, so it bothers me a little but they’re still so much more comfortable, soft, and cute than my other options that I don’t mind too much. Next time I might try a different style or smaller size to see if that helps!"

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)

I love the colors and

"I love the colors and the fabric, but there’s too much difference between the size XS and the S, so the XS feels too small, and the S a bit loose."

— M/Y M. (4/5)

Great material. Not a lot

"Great material. Not a lot of front coverage, but that's what I expected from this cut. It's a tiny, high rise thong. Covers the little belly pouch perfectly. Very sexy yet comfy."

— Samara H. (4/5)

Design is a bit too

"Design is a bit too slim for my liking. The material stretches quite a bit after a few washing cycles and becomes a bit too loose. For a flex design I would have expected a bit more shape."

— Tabea M. (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)

Too loose

"The fit is way too loose for my liking. I should probably have sized down. And the area in the crotch is way to small. the thong usually sits to one side so the rest is just out."

— Emilie S. (5/5)

"Honestly so happy with the purchase. They fit so well, very flattering and super soft."

— Ema P. (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)
