"This isn't a slip in that if you try to layer with it, you'll get bunching galore! (Exception: If you wear it OVER something sheer and long then you can layer with it, but I'm not sure if the top layer can be called a slip.) Either way, the fit is true to size, unless you are really busty or hippy. For me, the shoulders were a bit wide, but I have narrow shoulders, so for most that shouldn't be a problem. The material isn't cheap looking - which velvet can be - but the dress is eerily reminiscent of something Kelly Bundy would wear. (Which isn't a bad thing.) Looks great with tights, boot, and a hipster belt."
