Starlets kept it clean (and cool) at Nickelodeon's 2011 Kids' Choice Awards.

Some of the most notable red-carpet looks included those of Heidi Klum (who looked chic, and a bit edgy, in a Gucci LBD with heavy embellishments along the shoulders and collar and platform wedges), Selena Gomez (who kept it casual in a pastel-splashed, geometric tank and short ensemble from Christian Cota) and Miley Cyrus (who ditched her hipster duds for a breezy Dolce & Gabbana maxi dress).

The Hilton sisters looked abnormally conservative (and un-flashy), blending into the background in neutral dresses and accessories.
