At a sleek New York City downtown loft last night, makeup maestro Francois Nars launched 15x15 , an oversized coffee table book featuring artsy portraits of his favorite fashion friends -- such as Marc Jacobs , Olivier Theyskens and Shalom Harlow -- inspired by beauty's most iconic moments and star NARS products.

Created to commemorate the 15th anniversary of the edgy beauty brand, only a super limited 1500 copies of the book are printed, but you can purchase the stunning fashion portraits and other artwork created by the celebs on the website, 15x15Project.com, which launched last night and runs live until December 12th.

The most amazing part? 100% of the proceeds will be donated to the 15 chosen charities of the highlighted celebs.

At the stylish soiree, Jacobs proved that real men can wear skirts (or kilts, to be exact), as he showed up in a black, knee-length number that looked great next to his partner Lorenzo Martone's two tone jeans.

Transsexual queen Amanda Lepore glittered in a clingy Marilyn Monroe-esque gown with matching crystallized Louboutin heels.

Not to be outdone, Francois Nars arrived with his socialite muse Daphne Guinness, who teetered in Alexander McQueen fantasy ballet heels and a whimsical fairy outfit straight out of the pages of a costume photo shoot. Also in tow was Nars' 13-year old French bulldog, Marcel.

"I want to show that you can play with makeup!" says Nars.

So what NARS products do the celebs like to play with most? While Lepore opts for Jungle Red Lipstick because "red is the classic shade of glamour," supermodel Amber Valletta prefers the nude beige Belle de Jour Lipstick since it's "effortlessly chic."
