this is my go to when needing new underwear.
Size: 3X-Large, Color: Black/Navy/Dark Purple/Red
Love these boyshorts for women. They're so comfortable, no crawling and breathable. I recommend for plus size women who has legs rubbing together causing irritation. Nice price as well. This is my go to when needing new underwear.

Great!
Size: Small, Color: Black/Heather Gray/White/Nude
Comfy, good fit, good quality cotton and flat seams around the crotch. Normal size small. I wouldn’t wear these with yoga pants, but nice under looser fitting garments. I would buy more colors.

There is a seam up the front. I think perhaps it being seamless would be better.
Size: Medium, Color: Black
Like anything off Amazon I wasnt expecting anything perfect and ready to have to mail it back. Pleasantly surprised by the softness and durability. The waist band isn't to small on a medium so it fits actually so comfy. I wear them as underwear and as shorts for my skirts n dresses. Id recommend but I say size up if you want a comfy fit. But down if you want a fitted fit fit. Comfy still is fitted but better feeling on if that makes sense. Also the crotch of the shorts/undies has essentially extra fabric sewed in creating that nice comfort. Ill snag a photo when I have time.

Product varies from package to package
Size: X-Large, Color: Black/Navy/Dark Purple/Red
Over a two year period this is my 4th purchase. They started as sleep shorts and have replaced other underwear most of the time because they are comfortable and the quality is pretty good. However there are differences in between every package. The length has varied up to an inch, the material has changed, and some are slightly tighter than others. That said it works for me. I am a side sleeper and sometimes the side seam bothers me.
