(source: style.com) NEW YORK FALL 2007 FASHION WEEK PREVIEW Foreign Exchange Alice Temperley has big shoes to fill. The Tuesday 2 p.m. time slot that formerly belonged to the Marc by Marc Jacobs collection is now the Brit import's. Jacobs is taking his secondary line to London, where his new boutique is set to open on Mount Street in Mayfair later this month. And he's not the only one hitting the road: After two seasons as a solo act, Nathan Jenden has landed on the London schedule, while Mary Ping and Matthew Ames are trading places. The New Yorker has set her sights on Paris, and Ames is making a homecoming, returning to Gotham from the City of Light. Photo: Stephan Jaklitsch Design, Inc.
