Everything about Erica Davies’ debut is a declaration of independence. This is the Welsh-born Angeleno’s first solo project after eight years of designing for Richard Tyler, Marc Jacobs, Sportmax and BCBG Max Azria. Her presentation late Wednesday night at MOCA’s cavernous Geffen satellite building in downtown’s Little Tokyo, away from the dueling fashion week sites, was unique, too. In lieu of a formal show, her uncomplicated, cool London-L.A. girl clothes were projected larger than life on a 15-foot wall. The six-minute short documentary by filmmaker Clement Jolin, also available as a promotional DVD, was as straightforward as the clothes. As a pair of models walked the red-carpeted lounge of the decaying Ambassador Hotel, former home of the legendary Coconut Grove, the lens cut to the details that define Davies’ focused 20-piece collection: the silver nail heads studding the low-slung back of a plum jersey halter dress; the six buttons lined up on a tailored, cotton canvas jacket cuff; nickel buttons closing an off-kilter side pocket on pants. These are just great, smart pieces for Miss Independents anywhere.
