sexy brand new bondage wrap little black dress

ordered this online from the divided section on H&M thinking that it would fit but it's a taaaaad too tight for my liking. my loss is your gain. never worn out only to try it on. even though this says it fits a size 8 which would be a M I would say that this fits best a usual size 4 or a S. 94% polyester 6% elastane.
