I love legggings! I wear them almost everyday under a dress or skirt. These leggings are the best ones I have found. They are thick but not like sweatpants, they are strechy but keep form. I usually wear a size M but I've gained a little weight in the last year so I was going to get a L to be comfortable. However they were too long (I'm 5' 7'')! I bought 4 more in M and love them. :) Best leggings out there!!!!!
