Those in the heart of the inner west can head to Newtown's Costume Party for a great variety of outfits, accessories, wigs, face paint and special effects makeup. There's so much stuff that it can be hard to know where to start, so head to the King Street shop and get exploring. This joint has every theme covered — from Harry Potter to hippie disco get-ups.

If you're heading to a sporting event, it's perhaps best to leave the costume weaponry behind — but keep the huge range of swords and lightsabers in mind for another occasion (there'll always be one, whether you're expecting it or not). Overwhelmed with all of the choices? You can't go wrong with an animal onesie, as long as it's not too hot.
