LONDON APPENINGS: Condé Nast U.K. has created an iPhone app to help shoppers navigate London’s streets on the evening of Thursday, Sept. 8, Vogue’s Fashion’s Night Out. The app, Vogue FNO London, is free of charge and lists participating stores, special events, and a Google map that highlights the evening’s retail hotspots. It will be updated regularly in the run-up to the event. In other Fashion’s Night Out news, Coach plans to trumpet its arrival in London’s Mayfair with an event at its flagship store at 41 New Bond Street, hosted by British Vogue editor Alexandra Shulman. Earlier in the week, Gwyneth Paltrow will be the special guest at a dinner to mark the opening of the Coach store.
