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.

Genuinely comfortable and practical for everyday wear

Color: A-5pack, Size: Large, Color: A-5pack, Size: Large

I am very impressed with the FINETOO Boyshort Underwear for Women. These are extremely comfortable, even after wearing them all day. The cotton material is soft, breathable, and feels great against the skin without causing irritation. The cut is well designed and offers full coverage that stays in place without riding up. They are very wearable for everyday use, whether lounging, working, or running errands. I also appreciate that they do not create noticeable panty lines, which makes them easy to wear under different types of clothing, including leggings and jeans. Durability has been excellent so far. I have washed them multiple times, and they have not shown any signs of wear, stretching, or fading. The stitching has held up well, and the fabric still feels just as comfortable as when they were new. The color variety in the pack is another plus. The colors are cute, practical, and easy to mix into a regular underwear rotation. Overall, these boyshorts check all the boxes for comfort, durability, and everyday wearability. I would definitely recommend them to anyone looking for reliable, full coverage cotton underwear. A few are missing from my screenshot as I had already worn them!
