GUESS Dress- Black and grey strapless

Form fitting, thick but very stretchy material. Tons of compliments from these. Has non slip strip along the top so that it doesn't slip down. Small metal guess logo on the front left side and on the zipper. Unfortunately a small no longer fits, otherwise I would love to keep these. I have two: a red/black which I wore once and black and grey which I wore once. Included a photo from the brand of the red version. There is no damage to either dress, but the black and grey one has one of the inner hanging straps severed, likely because it was annoying me, if I know myself.
