BCBGMaxazria Black Cowl Neck Ruched Side Dress or Top Size Large

BCBGMaxazria Black Cowl Neck Ruched Side Dress or Top Size Large, NWT, bought as a dress but it’s very short and very sheer (see photos), would make a great top! The cowl neck has a twist detail and the side is ruched. The tag says large but it would fit a medium better.
