Could be longer in the legs but that’s my preference
Size: X-Large, Color: Set-un2
Very comfortable just wish they were a little longer

Perfect for my body and fit preference, plus COTTON
Size: X-Large, Color: Set-unbl
Update: Different color packs fit differently. I've purchased two packages, one all-black and one black with the colorful waistbands. The all-black are a little smaller. IMO the all-black run a half to a full size small, and the black with the colorful waistbands run true to size.
Listen, all of our bodies and preferences are so different, but these are perfect for my body and my fit preference. They hit at my bellybutton and I would describe the length as short-boyshorts, but not hipsters. Most importantly, they're cotton, which my body reacts much better to these days.

They're ok
Size: Large, Color: Set-mu2
These are ok. I'm 5'6", 150lbs. I got a large. The colors are fun. The waist band is comfortable, fits well, doesn't dig in, and sits high enough to not affect a my C-section scar, but they constantly ride up.
