LONDON CALLING: Frida Giannini is lovesick for London. After cutting the ribbon on the newly refurbished Gucci store on Sloane Street earlier this month and cohosting the opening party at the Saatchi Gallery, the Gucci creative director has decided to shoot the brand’s fall ad campaign in the British capital. Photographed by Inez van Lamsweerde and Vinoodh Matadin in a north London studio, the campaign features Jacquetta Wheeler. “We’re in London, so of course I had to have an English girl,” Giannini told WWD. It will also feature non-English models Raquel Zimmermann, Natasha Poly and Freja Beha.The mood is similar to past seasons — “a continuation of Frida’s Gucci generation,” according to a spokesman, and will break in the September issues of American and international editions of Vogue, Elle, GQ, Harper’s Bazaar and Vanity Fair.
