Last night, Victoria Beckham stepped out in Hollywood to celebrate the launch of husband David's line for the Adidas Originals collection. An event hosted by a sports brand would be the perfect excuse to keep it casual, but Victoria pulled out all the style stops in a dramatic little black dress by British designer William Tempest and purple Brian Atwood platform heels. We hear that Beckham discovered the 24-year-old Tempest when she attended the Fashion Fringe Spring 2010 showcase of emerging designers at London Fashion Week. Since she single-handedly sparked the Roland Mouret revival and has everyone from Leighton Meester to Heidi Klum wearing her own label, we expect it won't be long until we're spotting other fashion A-listers wearing Tempest's structured dresses on the red carpet.
