The material is very nice. Ordered the exact size the chart said and they fit however if you have ANY butt at all they will be shorter in the back. My daughters "cheeks" hang out of the back and she has a tiny little butt (wears a size 4). It would be nice if they would allow at least a little extra fabric in the back for a rear end. If you have NO butt at all you'll be fine. Again the quality and fabric is great but the cut is for a straight girl with not even the hint of a curve. Aren't these made for athletes who have muscle??
