Hold onto your wigs and keys for this one: Rachel Bilson–the prime-time television clothes horse and one of the most Googles names in trendy celebdom–has no stylist!

And just in case you're still standing on two feet after that bombshell: those worst-dressed lists that terrorize so many Hollywood starlets? Bilson couldn't care less.

“I don’t believe in regrets,” she dishes, on her wayhome from a “quick” day-long fashion shoot for Genlux magazine. “I go to Sav-On in Cookie Monster slippers, you know?”

Since she broke big playing Summer on Fox’s The OC, Bilson, 23, has had plenty of opportunity to sell out her vintage-laden Valley Girl fashion roots for the chance at a first-name relationship with Fraser over at Kitson. That temptation is sure to grow, now that she’s nailed her first big film project: a remake of the Italian comedic drama The Last Kiss, co-starring Zach Braff, due to start filming in early summer.

To a small degree, fame has sucked Bilson into the orbit of modern luxury; she has a soft spot for Jennifer Nicholson and the retro-femme flounce produced by the Jerusalem-born Rami Kashou. And she loves the flowing, soft shapes by rising New York clothier Derek Lam.

“He’s great because he’s got his own thing going on,” Bilson explains.

But still: J. Lo Bilson is not. She does not worship at the altar of designer logos, instead preferring to slip into a pair of black-and-white Romeo Gigli peep-toe pumps from the 1960s. And her fashion hero is no supermodel, but her mother, an eclectic dresser who knew every little vintage boutique around their North Hollywood neighborhood and who instilled in Bilson a strong love for the luxurious, but also the gently worn.

“My mother is amazing when it comes to style,” she gushes. “She’s the first person to mix and match her earrings. She has a funky sense of style; she’s the best.”

In other words, Bilson likes a little history in her wardrobe. She prefers that her clothes take their cues from a bygone era…perhaps one in which boys blew bugles and gals wore giant hibiscus blooms in their hair. Her tastes aren’t cheap. Upscale little boutiques, like the eclectic, Japanese-run Shabon on Beverly Boulevard, take up a lot of Bilson’s
shoe-shopping time.

“I’m obsessed with shoes and bags,” she admits. “I’m a size five-and-a-half shoe, so I can find a lot of vintage shoes.”

Even Bilson’s social life runs more NoHo than Hollywood. Despite a well-documented relationship with photogenic co-star Adam Brody—a coupling that could garner a ton of free publicity with just one well-timed appearance at Guy’s—Bilson swears she’d rather stay in. (Bilson’s home, like her clothes, has a retro panache: she lives with her best girlfriend in the Los Angeles neighborhood of Whitley Heights, in a Spanish-style bungalow built in 1923. “The silent-movie stars had their homes in Whitley Heights,” Bilson says.)

And when she does venture out, Bilson insists, she’s more likely to bang her head at a rock concert than stuff an 80-person entourage into a paparazzi trap.

That said, she did attend the Marc Jacobs store openings in Los Angeles in March, gliding the red carpet and even looking a bit starstruck.

“Well,” Bilson says, “he does make beautiful clothing.” — Leslie Gornstein
