I hadn't bought leggings since the 90s so I wasn't sure what I was getting myself into.  But these are fantastic.  The tummy shaping panel is very wide and very flattering.  I'm 5'8" and 200lbs and the xl fit really well, though at first I wasn't sure.  They look really small but they fit well, though just a bit on the short side for me being tall.  I felt they were a little bit pricey, but it's definitely worth it.  Love them.
