Petra Nemcova at the La Perla fall 2013 presentation

Czech supermodel Petra Nemcova poses at the La Perla fall 2013 presentation at The Gallery in New York Thursday night. The gorgeous 33-year-old, who served as host for the New York Fashion Week event, wore her ombre-dipped tresses in a braided crown and flaunted her God-given assets in a sexy LBD cinched with an ornately-threaded red-and-gold belt.
