SHRINKING STAFFS: By today, staff reductions at Vanity Fair, GQ, Allure, Architectural Digest and Condé Nast Traveler will have been implemented as layoffs continue across all titles at Condé Nast. The largest layoffs on Thursday are said to have happened at the magazine with one of the company’s largest mastheads, Vanity Fair, where cuts on the edit side on Thursday were described as “sizable.” Among those said to have been let go were Heather Halberstadt, a senior editor who had been at the title for about 10 years. Vanity Fair last week trimmed about five people from its ad sales staff, including an advertising director. GQ on Thursday laid off about a half dozen people across its edit and business divisions, and, on Wednesday, Allure let go five across both divisions of the magazine, including longtime executive editor Susan Kittenplan. The total number of staffers cut this month is approaching 300, with most of those — about 180 — coming from the closures of Gourmet, Modern Bride, Elegant Bride and Cookie.
