NEW VOICE: In her latest role, Rachel Bilson will play a fashion editor at In Style. The actress will pen a monthly Q&A beginning with the May issue, answering readers’ style questions and revealing some of her favorite trends. The former star of “The O.C.” has been a fixture in the pages of In Style and was profiled in the August issue when she launched a clothing line with DKNY Jeans. When managing editor Ariel Foxman asks readers who has the best personal style, “Rachel Bilson’s name comes up more often than not,” he said. “They love her particular take on eclectic chic. So I thought wouldn’t it be fun to connect with Rachel with our audience, give her a place in the magazine to talk directly to women about her styling quirks and fashion obsessions.” Is the actress interested in a career change? “I am not planning on quitting my day job to be a full-time fashion editor, although I am really enjoying it and it intrigues me very much,” she said. “I’m actually flattered more than anything that people want to ask me questions about style. I am honored to do it.” According to her first column, Bilson’s spring favorites include Lela Rose for Payless flats, Lanvin sandals and Matta scarves with pompom edges — “a cool alternative to fringe.” — S.D.S.
