Blue Cutout Jumpsuit w/ Pockets

I wore this to a black tie optional wedding and got a million compliments - I wish it still fit! Blue 1State Small jumpsuit with small cutouts in the back (not too much skin, still classy), a zipper & clasp closure, pockets, and wide legs. I am 5'4" for photo reference. IMO, it's a big 'Small' size - could probably fit medium as well.
