Louis Vuitton threw a party in New York to celebrate the launch of the 40th anniversary of the lunar landing. Any reason to party, right? A handful of PYTs showed up, most of them wearing at least one piece from the house. Jessica Szohr wore the Fall '09 platforms with a lace dress and military jacket; Cassie rocked the green tulip skirt and Loubs; Miranda Kerr carried the gold clutch along with a ruffle dress; Whitney Port looked sophisticated in a Rachel Comey LBD and pearl chain necklace; and a pregnant Adriana Lima wore a misty chiffon dress. Only one can be most Fab, who's it gonna be?
