I am the second owner, bought this for an event but ended up never wearing it. It has only been tried on by me and has been sitting in storage ever since.

There is one tiny mark on the inside of the dress which must've been from a hanger. It is absolutely not noticeable when worn. Picture included. Other than this the dress is slightly wrinkled from storage which should have no adverse affect on the dress.

I believe it would fit a usual size M from IW, so around a 95~cm bust and 76~cm waist.
