I love these leggings.  I ordered them in chocolate.  Following other people's recommendations, I ordered a size up; a Med/Lrg.  I usually wear a small or medium.  But the M/L fits great!  They are thicker and you don't have to worry about seeing anything through them.  They shape your tummy and legs nicely.  In fact, no muffin top at all!  I would definitely recommend these, just be sure to order a size up.
