H&M X Mugler Knot-detail one-shoulder dress - dark turquoise

Bought this and don't live in a location where I can return it :( Way too short and tight for my tall and curvy self, marked XXL and would probably fit a size 12-14 best. Tried on once and will send in original shipping packaging. Description below from H&M site. -- Designer x H&M. Short, figure-hugging, one-shoulder dress in soft, crêped viscose jersey and sheer mesh. In the recognizable designer style, this dress is cut from skin-baring panels wrapped around the body with stunning, all-over draping. Extra-wide ties at neckline and hip. Asymmetric cut at top, stand-up collar, and one long sleeve ending with a detachable glove with concealed snap fastener. Concealed zipper at one side with a star-shaped zipper pull.
