FASHION : A Lock on Star Hair

Robin Williams, Dustin Hoffman and Steven Spielberg have something in common besides all being part of the new movie “Hook.” They have Cristophe, who cuts their hair. But when “Hook” opened this week and the three celebrities were all over the entertainment news, did they call Cristophe for a quick do? “Not one of them,” he reports. “They like to keep things simple.” Spielberg’s overgrown coif was particularly noticeable during one TV interview. In fact, it looked like he hadn’t combed it in days. “That’s possible,” Cristophe conceded. “They all have other things on their mind. They all have families.” As for Hollywood’s star hairstylist, whose own shoulder-length locks are about as long as Hook’s these days, he may be appearing in front of the camera soon. He’s been asked to play himself in a cameo role for a movie about the beauty biz.

* TOURIST SEASON: New York designer Todd Oldham was in town finishing a special teaching project at the Otis/Parsons Art Institute. Afterward, he did the L.A. thing--attended a screening of “Rush,” went to an intimate dinner party for filmmaker Pedro Almodovar at Cafe Mambo and went shopping. He says his biggest thrill was spotting Demi Moore on Rodeo Drive and Katey Sagal at the Rose Bowl flea market. Oldham is getting to be a celebrity himself. He was recently named the 1991 recipient of the new talent award by the Council of Fashion Designers of America. Other honorees are Ralph Lauren for lifetime achievement, Isaac Mizrahi for women’s wear, Roger Forsythe for menswear (a posthumous recognition), Karl Lagerfeld for his Chanel accessories and Mary Lou Luther, former fashion editor of the Los Angeles Times, for her journalistic contributions.

* BLAST FROM THE PAST: Peggy Moffitt, the late L.A. fashion designer Rudi Gernreich’s favorite model and muse, has spent the last year putting pen to paper recording their glory years in the ‘60s. Her tome, “The Rudi Gernreich Book,”, is now on the shelves at Rizzoli and other local bookstores. It is filled with photos of Moffitt and Gernreich, most of them taken by her husband, William Claxton. A book-signing party is scheduled Tuesday from 4 to 7 p.m. at Theodore in Beverly Hills, with a collection of Claxton’s photographs also on display. Moffitt will be there in all her period-fashion glory to greet her legions of new, young fans. “The people who come up to me now understand what Rudi and I were about,” she told Listen. “They get it even if their mothers didn’t. They understand that modern fashion is fun and witty and anti-pretentious. It is not about how much money it costs.”

* Think Pink: If you’re looking for a special Christmas color, may we suggest pink? Walter and Carol Matthau seem to like it. They hosted a very pink and very private Christmas party last week at Tiffany & Co. in Beverly Hills. Asked to create the store’s Christmas table setting exhibition this year, Carol selected everything from the gold cherubs to a tree made of pink roses and the Princess Astrid china. She wore pink, of course, to greet the 80-plus guests, who included George Burns, Suzanne Pleshette, Carol Channing and Roddy McDowall.

* IS IT REAL OR IS IT TV?: In next Thursday’s extended episode of television’s teen drama “Beverly Hills, 90210,” Brenda (Shannen Doherty) gets a Christmas job at a fashionable boutique called Tracey Ross. What a coincidence. The location is the real Tracey Ross in Los Angeles. And Doherty, says a T.R. spokesperson, is a regular customer.
