While we’re still waiting for stylish Brit Victoria Beckham to start rocking Christian Siriano’s designs, the Project Runway winner has teamed up with another English singer to show off his new mini clothing collection for Puma. Shine chanteuse — and Kanye West collaborator — Estelle helped Christian unveil the first item from the fifteen-piece line at her record release party at a Manhattan club last night. Siriano created her distinctive ruffle-neck dress by deconstructing three existing Puma tanks. What’s more, he’s dubbed the R&B artist a muse. He tells PEOPLE, “For me it’s really exciting because it’s great to work with an artist that wants to be more creative and more fashion forward. That’s why I love her. I mean how fabulous is she?” We definitely think the dress is pretty fabulous and can’t wait to see more. Tell us: What do you think of Christian’s dress?
