A few weeks ago, I asked for ideas on what to wear for circus-themed fancy dress. I didn't go in fancy dress in the end, but about a quarter of the audience did. I can therefore report that the key component of a circus-themed fancy dress outfit is a top hat. The top hat is ideally worn with a corset and a tutu, but can go with just about anything, and is in itself enough to brand you as a circus person. Failing a top hat, one needs to wear a large floppy ruff. The truly adventurous don a golden mane.
