This week, we're switching gears from the dressed-down festival fashion of Coachella to full-on red-carpet wear. We couldn't help but be drawn by the glamour of the Tribeca Film Festival, where we spotted the likes of Emily Blunt and Leelee Sobieski, while LA film premieres drew out style setters like Ginnifer Goodwin. Across the pond, Scarlett Johansson donned a flower appliqué Prada strapless for the UK premiere of The Avengers. Inside, there's more from our style stars — like Nicky Hilton showing off a printed Topshop frock. Click on for the rest of the standouts.
