Any unique ideas for a fancy dress costume?

a group of about 14 of us girls have to dress up for competition in irish college, but we don't know what to go as. it has to be unique and original and preferably hand made. for example last year we all dressed out as crayola crayons. (and we won) we all wrapped different coloured card around us with 'crayola' written down the front and we had little cone shaped hats. we were thinking of going as candy bars and lollipops. any other ideas?
