11: PRADA "WAIST DOWN: SKIRTS" OPENING IN L.A.

Young Hollywood made tracks to the Prada Epicenter store in Beverly Hills to celebrate the opening of the "Waist Down: Skirts" exhibit. Over 100 skirts were on display, hand-selected from the company archives by party hostess Miuccia Prada. Although the show had had prior runs in Tokyo, Shanghai and New York, a creative group that included Rem Koolhaas designed the exhibit to change with each store. Of course, there was practically more Prada on the party guests, who included Eva Mendes, Patricia Arquette, Nicole Richie, Courtney Love, Lake Bell, Amber Valletta, Molly Sims, Amanda Peet, Alicia Witt, Jaclyn Smith, Ali Larter, Garcelle Beauvais-Nilon, Kristen Bell, Jaime King, Jeri Ryan, Angie Harmon, Heather Graham, Paris and Nicky Hilton, Rebecca Romijn, Lindsay Lohan, Monet Mazur, Taryn Manning, Rachel Zoe, Michelle Trachtenberg, Dita Von Teese, Lyle Lovett, Dustin Hoffman, Giovanni Ribisi and Sir Ben Kingsley.
