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.

Cotton panties need to be the standard- these are amazing!

Color: C-multicolor(6 Pack), Size: Medium

SO comfortable!! I’ve never owned a pair of 95-100% cotton underwear and I’m never going back. These are so breathable, soft and well made for an affordable price! The lacey detail is so cute and feminine. I got the mediums cause I don’t like my underwear squeezing me but don’t want them too loose either. After washing and drying they fit nicely. They hit at waist as well which I love. Would definitely recommend!
