My personal favourite fancy dress costumes this year are listed here, and it's always encouraging to see such creativity and variety!
The Lost Woodsman (above) has a moving eye (!) and some amazing hands made from leather gloves and sticks - Find the fantastic tutorial here.
A couple of amusing costumes with a French cookery theme. If I told anyone I was going to dress up as a croquembouche I might get a funny look, but I think it works surprisingly well!
Egyptian God and Goddess fancy dress, with intricate masks - see how much work went into them by clicking here.
And just for the adorable factor, here's a little granny costume!
