I'm about 130 and 5'3" and the medium is perfect.  Nice in the waist (high is what I like) and real comfortable.  Just got today and wearing them as I write!  The design lined up nicely (I was worried it would not be), so I'm a happy camper.  The "Sparkle" is the best design for me but maybe I'll check out some others now that I lucked out on this one.
