Fabulous dress from Guess.  Most likely a D Cup Bustier, generous stretch.  Laid flat, measures 18" underarm to underarm, 15" at waist, 20" at hip - there is a lot of give to this dress so it would most likely accomodate another 2" at the bust and hip.  Fully lined.  Smoke free/pest free home.  Ships fast.  Thanks for looking!
