love the way the pants don't have seams or pockets which makes the pants fall nice and smooth and not bulky. I use these for PJ's. The only complaint is that the waist band is tight for me because my body type is very straight and my hips and waist are kinda the same size. A medium would be WAAAY to big up top (the small is perfect and I am 5'6". In reality, most people with my hip width probably have 24 -26 in waist, so it will not feel as snug. They are work fine and I kept the set, but I prefer a looser fit around the waist (I often go up a size in yoga pants so that the waist is looser). I sense the SKIMS brand is more for curvier women though, versus my "straight" body type. Fabric is wonderful.
