Reviews

Amazing Undies but colors/ sizing vary

"This was my first purchase from OB that I loved- I am happy I stuck it out and kept trying. I would definitely size up in this style, and recommend this over the traditional core thong. Comfy and stylish, great fit once I found a style/ color that worked (as colors vary in sizing as well. ) 10/10"

— Kehana K. (5/5)

I love the fabric, it

"I love the fabric, it is very soft. I basically can't feel it when wearing it, also it is not visible much under clothing. If you expect them to stay skin-tight (in a comfy way) I recommend sizing down 2 sizes. I sized down 1 size, and they still get a bit loose over the day. I am usually an XL, ordered L this time."

— Andrea R. (4/5)

New Go-to!

"My new favorite brand to purchase underwear from! The material is soft and comfortable. The shape is like that of some more expensive underwear brands I know, but for a far more economic price."

— Mackenzie H. (5/5)

What a find! Completly unexpected,

"What a find! Completly unexpected, that thong can be stretchy but organic! The model of it is a perfection - it covers the parts that needed and at the same time nothing digs in to your sides. The texture is soft and comfortable. And the color! Summer vibes :)"

— Alla V. (5/5)

Great, thin and soft material.

"Great, thin and soft material. Generous fit, probably true to size or slightly large. Somewhat small gusset."

— Friederike P. (4/5)
