Due to my excellent work at pulling off Halloween, i have been tasked with organising a fancy dress day at work for our current charity Young Minds and i am at a bit of a loss for theme ideas, It needs to be something everyone can get on board with, young and old, big and small, inexpensive and fun but also practical and not hinder our work in a busy food shop. We already have a yellow t-shirt day coming up so i am looking for a proper costume theme, can anyone give me hand?
