Kirsten Dunst, Kate Bosworth, Rashida Jones, Gia Coppola, Angela Lindvall, Samantha and Victoria Traina and other lovelies came out to fete Proenza Schouler and wearing Proenza Schouler, at a dinner party Thursday night in a private home on Mulholland Drive, with the lights of the San Fernando Valley strung out below.

The passion fruit margaritas were a-flowin’, and why not? Proenza Schouler designers Jack McCollough and Lazaro Hernandez have had quite a few weeks, picking up the Women’s Wear Designer of the Year Award from the Council of Fashion Designers of America earlier this month, and then celebrating their 10th anniversary earlier this week in New York, at a party hosted by Barneys chief executive Mark Lee at his Chelsea apartment.

Thursday’s event in L.A., also hosted by Barneys, had a casual, friendly feel, held at the modernist home of art dealer Mark Fletcher and Tobias Meyer, auctioneer for Sotheby's, with a buffet supper catered by Farm Shop.

“Barneys is like our family,” McCollough said, hanging outside by the pool. Indeed, Barneys has been with the duo since the beginning, purchasing their Parsons senior thesis collection in 2002. Proenza Schouler staged its first major runway show at the National Arts Club in 2003. I remember being at that show, sitting next to Tim Gunn. That was before his “Project Runway” fame. Back then, he was just a proud Parsons professor.

That first collection, including the bustier tops, tissue T-shirts and structured, oversized outerwear that would become Proenza Schouler signatures, has been reissued for today and will be available exclusively at Barneys New York this summer.

“We had to totally redo the patterns because they really didn’t fit,” McCollough said. “We sewed everything ourselves and they were barely clothes. We’re lucky they made it down the runway.”

McCollough was happy to be visiting L.A. where his sister, Kate, a set designer who works on creative projects for Proenza Schouler, and his brother Doug, a furniture designer, both live. McCollough and Hernandez, who are both design and life partners, are in town until Sunday, when they head to Beijing for another CFDA event. When they return to New York, it’s full speed ahead. They are opening their second boutique, in Soho, and moving into a new house in Brooklyn.

But this weekend they’re planning to relax. “Sleeping late, maybe a hike in Griffith Park. That’s the mind set right now,” McCollough said.
