Jason Wu says he was inspired by strong women for his Spring 2015 collection, and he had two in particular in mind: Actresses Charlotte Rampling and Diane Kruger. “They have impeccable style,” Wu says of the actresses, 30 years apart in age. “I imagined them in every single piece.” Wu presented what he called a glamorous take on American sportswear — casual looks in rich fabrics. He used silk organza, suede, leather and what he calls “silk canvas.” A suit that looked like denim was actually made of silk tweed. In dressier looks, Wu’s fabrics took on a shiny, sparkly veneer.
