Be as straight or as awesome as you like. It's up to you.
Choose a simple accessory or put together a whole outfit. Go retro, go sophisticated, go glam. Or get together with your workmates and select a theme. It's up to you.
Get the whole office on board, and strut your stuff on the day. Have a laugh, share your pics and see who comes top in the office catwalk stakes - but most importantly, text a donation to Oxfam. You'll not only look good but feel good too, by helping to change lives and end poverty around the world.
