A great idea again: customize accessories to your clothes with spray paints.
This way you can make i.e. comfortable shoes for dancing matching your ball dress ;-)
Or follow the ideas of Buy Nothing Day and revamp a by now shabby handbag to match your newest coat.
You also could have coloured one of your boots in red and fill it with some sweets ;-))
