Grey knit dress with ruching and high slit

Grey knit dress from forever 21, brand new with tags on! It is a bit sheer on the top, very stretchy. Looks as if it’s two separate pieces and it has a bodysuit under the skirt. The slit is very high, almost to crotch and the skirt is a bit asymmetrical. I can do a try on if you would like to see it on! Size medium but it can fit large.
