PRETTY AS A PICTURE?: Since nothing can be published in peace without a requisite book signing, Hamish Bowles donned one of his many hats Monday night and acted as proud author of "Vogue Living: Houses, Gardens, People" at the Calvin Klein store on Madison Avenue. As people lined up to buy the aspirational tome — including Delphine and Reed Krakoff, whose home is included in the 400 pages — Bowles admitted his own apartment was "undisciplined." "It's very Cecil Beaton, very dense, very cluttered," he said. Same goes for Calvin Klein designer Francisco Costa, whose Bellport, N.Y., home (or at least its outside) is featured in this issue of "Vogue Living."

"I'm so happy they didn't shoot inside," he said, feigning stress. "My house in Bellport is a mess. But my New York apartment is very tailored."

BIG SALE: The host committee for next week's Fashion For Action bash reads like a Who's Who of young New York fashion, including the likes of Jane Mayle, Charlotte Ronson, Adam Lippes and Shoshana Lowenstein. The benefit, to take place at The Rubin Museum of Art on Nov. 8, is in aid of Housing Works, and will feature a silent auction of clothes donated by such designers and brands as Marc Jacobs, Prada, Michael Kors, Narciso Rodriguez, Bottega Veneta, Diane von Furstenberg, Elie Tahari, Fendi and Giorgio Armani. Those who can't make the gala, which will be hosted by Rashida Jones, need not fret. The designer sample sale will continue Nov. 9 to 11 at the Housing Works Chelsea Thrift Shop. Fashion for Action raised $350,000 last year, and the aim is to bring that number to $500,000 this year.

JEWELS FOR JOES: Evan Yurman welcomed pals Mary-Kate Olsen, Mini Anden, Jacquetta Wheeler, Jeremy Piven and Kate Sumner to dinner and a concert by The Bravery at the Paramour Mansion in L.A.'s Silver Lake last week to celebrate the launch of his men's jewelry and watch collection for David Yurman. Like his dad, he finds inspiration everywhere. "I get inspired by myriad things: personal interests, rare stones, different textures....I keep an open mind and look for the unexpected in my everyday life," he said. Yurman chose to host an event in Los Angeles because of the support of the local community — and because Hollywood men like Piven aren't afraid to accessorize. "Men in L.A. understand jewelry, which is a testament to the West Coast's influence on design today," said Yurman. The collection starts at $1,000 and goes up to $30,000.
