Universal Thread Women's Corset Denim Dress Midi A-Line Sz LARGE Worn Once This dress is made with a “soft, stretchy denim fabric” made from 99% cotton and 1% spandex. It has a somewhat sweetheart neckline (Target calls it “asymmetrical”) and buttons down the front of the dress that are just for show. You can’t unbutton it to get it on and off—it’s a “pullover” style per their site—but you can adjust the spaghetti straps. Also, as its name states, it’s a midi length, measuring 53 inches long.
