this Sorry, is under party dresses, page 3, called katie prom dress. Can't link straight to it. I need a dress for friends 30th birthday party (at her house but invite says cocktail dress). I don't want to be too formal though. Have tried this on and its quite flattering just don't know whether will look a bit 'silly'. Have tried on another that looked ok in oasis but was black and more calf length so maight feel a bit boring/formal for a house party.
