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.

Comfortable, breathable, and flattering
Size: Small, Color: Pink/White/Khaki/Blue/Brown
I’m really pleased with this set of cotton women’s boxer shorts. The fabric is genuine cotton and feels lightweight and breathable without feeling flimsy or cheap. They’re comfortable enough to wear all day, especially if you prefer natural fibers. The elastic waistband is soft, comfortable, and also really cute, it doesn’t dig in or feel restrictive at all. The fit is true to size. I usually wear a small in underwear and these fit me perfectly. They feel secure while still looking sexy and relaxed at the same time, which is a great balance. I also really appreciate the earthy color palette, it feels calm, natural, and wearable rather than overly bright or synthetic. Overall, these are well-made, comfortable, and thoughtfully designed, and I’d happily order them again.

Lightweight and Comfortable.
Size: Small, Color: Pink/White/Khaki/Blue/Brown
These cotton boy shorts are really comfortable and soft. The material is breathable and feels nice on the skin, not itchy or tight. The size small fits true to size and stays in place without rolling up. I like the striped design and how they give good coverage while still feeling lightweight. Great for everyday wear and easy to wash. Overall, a solid and comfy underwear set.
