Bowie and his Spiders from Mars can move over. Dress code "Space Oddity", this Halloween London's coolest crowd lathered on the body paint and crash-landed at London's Metropolis strip club, like an invasion of sexy, otherworldly beings. Guests fixed their wigs at the Bleach London beach upstairs (sand and stripper heels proving a dangerous combination for some), while on the lower floors they pole danced to the sweet sounds of Geri Halliwell, surrounded by inflatable aliens. Mixing fetishwear with a whole lotta lurex, this year's costumes saw a space-age Spongebob complete with a silver bodysuit, "Oops I Did It Again" video Britney, and even a sexy R2-D2. One thing's for sure, Metropolis will be cleaning the glitter off the floor for weeks. See who made our top 10 best costumes below:
