Fit great, looked good, and felt nice.  But way too see-through. Had to return.  They would be fine if you were always wearing them under a skirt but I wanted to wear them to the gym.

A note on sizing: I'm usually a medium in most bottoms but a small in Spanx shapewear.  But based on comments here I ordered a medium for these leggings.  It was a perfect fit, actually tighter than my current leggings which are Athleta mediums.  So they are fairly true to size for leggings, but consider ordering up a size from your Spanx shapewear size.
