This fall's hardest-to-find red lipstick is bound to be P.S. Kiss, Lancôme's Pout-à-Porter limited-edition shade from designer Peter Som. The $24 lipstick has a dark red hue that Som created with Lancome creative director Gucci Westman. It goes on sale October 1 at Bergdorf Goodman, Nordstrom and Lancôme boutiques—but the waiting lists are already beginning. The New York Times reports that Bergdorf's list will soon open, but savvy shoppers already have been getting on the list by dialing 212-872-2740 for a spot.

Proenza Schouler and Behnaz Sarafpour both saw their Lancôme lipsticks sell out, and Peter Som's will likely do the same. Next up is Thakoon, whose lip shade will debut at his Spring 2008 fashion show in a few weeks. It'll then go on sale early next year.
