Fredrik Eklund, Nicole Miller, came out to celebrate Michael Gross’ new book “Focus”

Society and real estate journalist Michael Gross has spent his life writing about the going-ons of the upper classes. And so at a party for his new book, “FOCUS: The Secret, Sexy, Sometimes Sordid World of Fashion Photographers,” the best and brightest were there to celebrate with him.

150 socialites, models, celebrities and real estate folk crowded into the penthouse apartment at the Schumacher building at 36 Bleecker Street, which is currently on the market for $20 million. Notable guests at the event included Frederique Van der Wal, Debbie Bancroft, Edward and Henry Lambert, Nicole Miller, Susan Blonde, Nina Griscom, Tiffany Dubin, Barry Kisselstein -Cord, Peter Davis,  Pamela Taylor, Suzanne Donahue, Arthur Wayne, Jill Brooke, Lauren Ezersky, Patrick MacDonald,  Felicia Taylor, Roy Kean and Fredrik Eklund, who is listing the property with Douglas Elliman.

Guests wandered around the five-bedroom apartment, which features two wraparound terraces and a glass-enclosed solarium, sipping hibiscus cocktails, and snacking on hors d’oeuvres and sushi.
