I have bought Hue leggings before - and I love the double knit fabrics, so I ordered these leggings in a large (I am 5'3" and about 140lbs).  I think I could have ordered a medium, but I actually don't like them to be skin tight so this was great.  The fabric is a great weight and super comfortable.  Can go from dressy to casual depending on what you wear with it.  You won't be disappointed in these leggings.
