Industryites up on their fashion knowledge converged on the home of Heather and Skip Brittenham for a rare L.A. runway show featuring hot label Proenza Schouler. New York-based designers Lazaro Hernandez and Jack McCollough — who seemed perfectly happy despite a reported breakup a couple of months ago — jetted into town to mingle with industryites during a dinner and show presented by Barneys and Hewlett-Packard benefiting the Rape Foundation.

The carefully orchestrated event even took into consideration the fact that Hollywood types aren’t exactly punctual. Hosts Christina Ricci and Kerry Washington and nearly 400 guests, including Elizabeth Banks and Amber Valletta, were told that the show would start at 7:45 p.m., when it was really just a ploy to get them to the dinner on time. “The women are habitually late for everything, unless of course it’s for fashion!” said Barneys’ creative director Simon Doonan, who planned the switch. After the candlelit meal — during which Bob Gersh and CAA’s Tracy Brennan and Rick Kurtzman held court at neighboring tables — the attendees were treated to some fall clothes.

Although Hernandez and McCollough count Demi Moore and Marisa Tomei as fans, some guests were still in the dark about their highly praised line. “I’m not familiar with the designers,” said “The Upside of Anger’s” Alicia Witt, “but I love fashion. That, and it’s a great cause.”
