Elevated platforms Harlow Essex

It’s tough not to have a good time when it’s 75 degrees and sunny—but it wasn't just the warm temps that brought out Hollywood's most fashionable for yesterday's Revolve party in Los Angeles. Stars were also there to support Stand Up to Cancer (SU2C), the worthy cause that the fête benefited.

Held inside a picturesque private estate, the event drew celebrities like Jaime King (above, left), Sarah Hyland (above, right), Louise Roe (below, left), Jamie Chung (below, right), Molly Sims, and Olivia Culpo, each of whom dressed in pieces from the Revolve x SU2C collection, which includes ‘70s-inspired items from House of Harlow, Mara Hoffman, and similar Southern California-cool designers. Hyland once more killed it on the fashion front, rocking a brocade dress and complementary purple lip, while King sported a hot red number that paid homage to the days of Studio 54.

“I’m so happy to be at this event to support Stand Up 2 Cancer and Revolve. What they’re doing is amazing, ” Hyland said. “My mom is a 6-year breast cancer survivor, so this cause is very near and dear to my heart.”

Guests strolled around the mountainside venue, where plush, off-white couches were arranged to create a living room-like feel. For the fashion show—which stars like Chung and Fergie participated in—a translucent, elevated platform was raised above an endlessly pool. Oversized white balloons suspended overhead served as an extra punch of décor (above).
