Is that a Trench or a Dress?

I'm all about multi purpose pieces.  When I something I want the most bang for my buck.  A piece that can always give you multiple uses is a trench coat.  It can be worn the traditional way and double as a dress with a boujee high slit.  What clothing item do you use in more then one way?
