BRITS IN BULGARI: “It’s nice to go to a party and wear high heels,” mused Margo Stilley at a cocktail hosted by British Vogue and Bulgari at London’s Saatchi Gallery last week. The actress explained she’d been on hiatus from the social scene while shooting a gritty film in Barcelona for the past eight weeks, thus was happy to glam up in an Yves Saint Laurent tuxedo suit and a Bulgari diamond choker for the night. The party — in honor of Bulgari’s charitable campaign with Save the Children, “Rewrite the Future,” which aims to provide education for children in conflict-affected areas — drew guests including Princess Michael of Kent, Lady Helen Taylor, Dominic Cooper, Bill Nighy, Peaches Geldof and Natalie Imbruglia. While Imbruglia happily showed off the Bulgari spider web diamond brooch and flower-shaped ring she was wearing, nonfamous guests alike were able to get their hands on Bulgari’s wares during the evening. Guests could purchase the engraved silver rings and pendants Bulgari has created to support the charity, and peruse the collection of 18 one-of-a-kind Bulgari jewels and timepieces that will be auctioned for the charity in New York in December.
