'Project Runway's Christian Siriano goes ballet for Spring 2013: VIDEO

Brad Walsh

With his new video and print campaign today, Christian Siriano shows off the inspiration for his Spring/Summer 2013 collection: ballet movement.

Project Runway's season 4 champ enlisted his beau Brad Walsh to shoot the campaign film that features his whimsical pastel designs draped over dancers Katerina Eng, Isabelle Seiler, and Carolyn Lippert of the Jacqueline Kennedy Onassis School at American Ballet Theatre. "I wanted the video to portray the dancers as if each were dreaming about the costumes they'd be wearing in a performance," Siriano said in a statement. "I wanted this collection to feel as light, soft, and romantic as the dancers on the stage and in the painting, but modern enough to be wearable by today's elegant woman."

Some of Siriano's Spring pieces were taken for a spin on the red carpet during last year's awards season: Kaley Cuoco wore a pink one shoulder frock at the 2012 People's Choice Awards, and Carrie Underwood chose a pink and grey ensemble during her frenzy of dress changes at the 2012 Country Music Awards. See more of the designer's dresses come to life ballet-style in the video below.
