I got these in 2 colors - they are okay and there are no panty lines but I don't like them as much as Soma's no panty line ones - theirs do not ride up due to the rubbery strips on the leg openings while these do tend to ride up.  The good news is these are cheaper.  I normally wear a size 6 and the medium fit okay.  They do come all the way up to your waist, which I like
