Reviews

Favorite Underwear

"I wear these underwear literally every day. The rib fabric makes them extra fun and also extra comfortable, I love the fit, they are high waisted enough, which I would prefer a high waisted cut specifically, but I just go ahead and buy a size up and go high leg. I definitely recommend these and will continue to buy them again and again."

— Allison W. (5/5)

Almost perfect

"The fit and material of the core thong are pretty perfect. Soft and sleek and the cotton does feel high quality. Unfortunately after the first wash the elastic on one pair frayed and I’ve noticed wear on the seams of the gusset. I’m still happy with my purchase, but I’m not sure how long they will last! Maybe they need to be washed in an intimates bag or a more delicate wash…"

— Maia C. (5/5)

Love!

"So comfortable! The cut is cute too. The black is a classic neutral tone for everyday wear. I like that the look of them isn’t frumpy for a basic!"

— Kate M. (5/5)

I like the Material a

"I like the Material a lot. So far they are still keeping their form after they were washed several times. The colours are as depicted and the fit is nice."

— Anna S. (5/5)

Inexplicably long

"These are perhaps the most ill fitting underwear I’ve ever had. I’m a size 4/S and 5’7. I ordered a size small in these. They are HUGE in length - I could pull the underwear up to my ribs - that’s how long they are. The crotch area is weirdly loose - they’re just awful. Do not buy."

— Madeline (1/5)

Great everyday set

"Great everyday basics and such a nice mix of colors. Comfortable and flattering."

— Dana (5/5)

10/10. I love this underwear.

"10/10. I love this underwear. It is comfortable, the fabric is strong and soft, and there is plenty of stretch. I wear them everyday."

— Allison W. (5/5)

I bought flex thong M

"I bought flex thong M size a while back but they were to big for me. That’s why I bought these ones S size but they are a bit small. I guess these is a bit of size variation model to model and it’s hard to predict which size to get. Other than that they seem great."

— Tjaša T. (4/5)

Looking for a cotton underwear

"Looking for a cotton underwear and it met the expectations, although pretty thick seams so may show and not super stretchy. But not uncomfortable, the fabric felt good quality but like I said not super stretchy. But overall good purchase for underwear that are sustainable material."

— Sami M. (4/5)

Sizing is incorrect

"I wanted to love these cotton underwear and I have been switching to natural fabrics but I’m extremely disappointed that they do not last and they fit too small. I am a size medium wearing bottoms between size 28-29 so purchased a pack of medium thongs as the size guide recommended. However when I received them and wore them a few times with a few washes, they quickly began to shrink and now have holes in the seams. I’m disappointed in the amount of money I spent on these thongs and the poor quality. I was expected better for this price point."
