How to dress up as a dead school girl for halloween
Realise that you will not necessarily need to buy a costume.
You may use any old school or work tops and skirts, however note that you probably shouldn't use something you need. Try to borrow things rather than buy them.
As this is an outfit for one night only, probably, make your maximum spending limit a small amount, $8/ 5. Make the top of your dead school girl costume.
