Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.

Ehh
Size: Medium, Color: Multicoloured E-(5-pack)
Very thin, still comfy but very thin material. Super soft though. I've worn and washed and they have held up but I won't be repurchasing bc these are so thin

They’re fantastic!!!!
Size: X-Large, Color: Multicoloured E-(5-pack)
My clothing size is 16/18 and XL. Even though Amazon suggested a size XXL, I ordered my normal XL and they fit perfectly. The fabric for this style is 92% bamboo viscose and is amazingly soft and almost silky feeling. I had ordered a different boy short in this brand but they were 80% bamboo viscose and the fabric was significantly heavier. I returned those and ordered these.
