Party Ready Nails (Disco Ball Manicure)

Katy Perry's recent TwitPic of her disco-ball manicure was the beauty tweet heard around the world. Fashionistas flipped over the blingy nail candy, andy why wouldn't they? It's a totally unexpected way to gussy up your LBD for New Year's Eve. Here's where to get the Swarovski-studded mani done in NYC.

Shizuka New York Day Spa

Calling all party procrastinators: This midtown Manhattan spa, famous for its Geisha bird poop facials, will be open till 6pm on New Year's Eve. The disco ball manicure costs $180 ($150 if you mention TONY through January 1).

Note: If Katy Perry's blingy disco ball manicure look is a little too extreme, or too pricey, a look for your New Year's plans, try our NYC nail salon's Crystal Manicure ($65), a much subtler version of the above.
