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.

Flattering fit
Color: White, Size: Large
Flattering fit and comfortable. Material is a bit see through but that doesn't bother me. Great value for a nice looking shirt.

Super Soft and Comfortable, Just Not the Most Forgiving Fit
Color: Purple, Size: X-Large
This top is incredibly soft and comfortable, which was the first thing I noticed. It has a really nice, lightweight feel that is easy to wear and not too thick or heavy, making it great for everyday use. Fit is true to size, but I would not call it very forgiving through the midsection. It is not cropped, but it also does not have much added length, so it hits in a way that can highlight the stomach area more than expected. Just something to be aware of depending on how you like your tops to fit. I know the material blend can pricey but still not sure I would say it's value is worth it. I like it, but I odn't love it. The purple color is better in person than the picture though! Overall, it is a great basic if you are looking for something soft and comfortable, just know it leans a bit more fitted than flowy.
