I ordered 6 different pairs of black leggings online, these Splendid brand were the best!  Very soft with a wonderful fabric, there is a thin terry lining which makes them thicker than other leggings, the size (XS) and length is perfect for me (100 lbs, 5'1").  I just wish they came in more colors, but I'll look for Modal fabric in the future because I think that's what makes it so soft.  My only complaint is the waistband, it's too high and skinny elastic, but I wear it folded over and it's fine.  Splendid - please make a low rise wide waistband legging in more colors!
