This midi-length dress, which can be dressed up or down, is 100% viscose. It has a sewn-in, drawstring tie at the waist that makes it incredibly flattering. Pit-to-Pit measurement: 23", but is actually even a bit roomier than that because of how it hangs. Everything I sell is from my personal closet...and I basically like to live my life pretending I'm in an English garden. So if you like this, make sure to check out the other things from my closet clean-out. It hangs beautifully. EUC. Non-smoking home.
