We think Erin Wasson is preparing to take over the world. First, she was splashed all over fashion mags with pal Alexander Wang, helping him style his first, breakout collection. Next, in our latest Victoria's Secret catalog, Erin seemed to be the model d'jour. And now, we're pretty sure she's taking Kate Moss on for the title of coolest supermodel to walk the earth. Although it sort of looks like she forgot her pants.

We are smitten about this Nina Ricci dress that she paired with Emma Cook for Topshop boots and a vintage Escada belt. As you can see, it's all about mixing the high and the low. If you can master that, then you've mastered the supermodel way of dress.
