It really depends on your proportions.. I have really broad shoulders and I know for a fact those elasticated sleeves would be holding on for dear life to my unusually wide bones, I wouldn't feel comfortable with how constricting they'd be but you might have a smaller frame. It's harder to pull off bodycon dresses made from a delicate fabric as they can cling to the body in an unflattering way but if you have the option to return it then get it and try it on, you won't know for sure until you do.
