Hosted by Vogue magazine, the soiree gave a fashion preview of Lim's new looks which have yet to hit stores!
Rachel Bilson wore a rose-gold lamé, double-breasted shorts suit from the designer's Resort 2010 collection, which despite its astronaut potential, looked surprisingly chic.
The petite actress later removed her jacket, but finished her look with cream heels and a Longchamp snakeskin print clutch.
Kristen Bell opted for Lim's metallic party frock in a darker hue, specifically a space-age, mercury gray that perfectly suits the anniversary (July 20) of man landing on the moon.
Rapper-turned-actress Eve picked a look from Resort 2010 as well, showing off her great gams in a gold and black lace mindress.
Later on, Liela Moss and her band The Duke Spirit took the stage. Moss rocked out in the designer's blinding gold top with extra-large sequins -- the same one that Vogue's West Coast Senior Editor, Lisa Love had on! -- paired with tiny leather shorts.
With metallics and a hot band performing, this wasn't your usual store party. Looks like Lim knows a thing or two about fashion and fun!
