I have a shirt black skirt which will do.
So I need a shirt (I'm thinking just a plain white blouse? something cheap as it will be ruined for effect)
Tie (primark?)
Knee length socks (black? stripey for effect? white?)
Shoes (would simple plimsoles do?)
What should I do to my hair? I was thinking messed up bunches?
The night out will involve a few drinks in normal bars (so can't go too OTT!) and then a goth night club.
