In a film directed by fiancé Michael Polish, Bosworth stands atop a piano and sings a sultry rendition of "Winter Wonderland" whilst wearing a backless sequined dress that she and Topshop designed just for the occasion. The lighting is moody, the atmosphere is hazy, and yes, that is Bosworth's actual singing voice. If this scene looks a little familiar, that's because it was inspired by another vampy blonde's legendary musical performance a few decades back: Michelle Pfeiffer's "Makin' Whoopee" in the 1989 film The Fabulous Baker Boys.
While Bosworth's shoes, dress, and makeup will all be available in some capacity on Topshop.com, those registered on the site are in for an even cooler treat: a personalized holiday message from the actress via the video's interactive capability.
"This project brings together two important aspects of my life: cinema and fashion," Bosworth says. "I hope everyone enjoys watching it as much as we did making it."
