At Fashion Week, everybody needs a buddy. Anna Wintour arrived at yesterday’s shows with the new editorial director of Conde Nast, Thomas Wallace. Like Paris Hilton, interior designer Celerie Kemble brought along her pocketbook-size dog, Anchovy (though her more frequent companion is boyfriend Boykin Curry).

Other ladies leaned on their significant others. Jessica Seinfeld had her eye on the clothes and her hand on her husband Jerry Seinfeld’s knee during Narciso Rodriguez’s runway presentation. Donald and Melania Trump both kept total concentration on the models gliding past them. And let’s not forget the valiant Jay-Z, who waited with Beyonce Knowles for more than an hour to see the Marc Jacobs show Monday night at the Armory.

Celebrities are often seated together, and so it was that soprano Renee Fleming, watched the Carmen Marc Valvo show with actress and singer Vanessa Williams. Jessica Capshaw found company in Catalina Sandino Moreno at the Michael Kors show. Perhaps the Hollywood veteran Miss Capshaw (daughter of Steven Spielberg and Kate Capshaw) advised Ms. Moreno on what to wear on the red carpet at the Academy Awards – the Colombian beauty is nominated for best actress for her role in “Maria Full of Grace.”

But the happiest of fashion-show buddies are the longtime female friends like Jennifer Creel and Tory Burch (siblings, like the Olsen twins and the Hilton sisters, also fall into this category). Who better to “shop” with than someone intimately familiar with your closet?

The New York Landmarks Preservation Foundation held its annual luncheon yesterday at Christie’s. The dean of the Yale School of Architecture, Robert A.M. Stern, spoke energetically about how to create new construction in historic settings. While “occasional explosions of genius have enriched us,” he said – throwing slides up of Frank Lloyd Wright’s Guggenheim Museum in New York and Frank Gehry’s Guggenheim in Bilbao – “not every architect is a genius, and not every building can or should be explosive.”

At Harvard, for instance, Mr. Stern designed the business school’s student center to complement the redbrick Georgian buildings that dominate the campus. He is now at work on a new southern facade for the business school’s library, once again honoring the Georgian style (“or, as some folks like to say, ‘recognizing the brand,'” he said). His final point: “Every period can do a Georgian building,” he said, pausing for his punch line: “They didn’t know that at the Harvard Club on West 44th Street” (a dig at the club’s recent addition).

Listening attentively was the director of the Whitney Museum of American Art, Adam Weinberg. The museum is planning an expansion, and as a hearing last week demonstrated, neighborhood residents are paying very close attention to its impact on its surroundings. Lots of people in the room wanted a word with Mr. Weinberg on the subject, including the Whitney’s historical preservation consultant, Bill Higgins, and the chairman of the New York City Landmarks Commission, Robert Tierney, who, upon spying the press, stole Mr. Weinberg away for a private huddle.
