Nicole Richie attended the 2011 Environmental Media Awards in a sunny yellow mini-dress with nude ankle-strap pumps and a tan clutch and while it would have been infinitely easier for me to make punny jokes if she were wearing green, she didn't, so I'll work within the confines of reality. This is a little cheery breezy happy fun, and a little Big Bird goes to a charity gala.

What do you think of Nicole's outfit? Sexy or Sesame Street?
