I know it's too late for Halloween this year, but it's never too late to start planning for next year, right? There's a new "fancy dress" site from the UK that's one of the most comprehensive I've seen.
They've got everything you need, from costumes to wigs, props to magic tricks, and disguise accessories.
Can't see having something eternally just to wear it for a few hours? Londoners can hire a costume from a dozen different categories from?animals and mascots?to United Nations national wear and western.
Even us "uncivilised Yankees" can partake of the fanciness - they ship worldwide. You'll find the most popular costumes for kids and a bigger selection of masks than anyone should have. But you're bound to have more fun than most, too.
