We can’t stop thinking about shopping for our fall wardrobes, and Kristen Bell’s minidress that she wore last night to the Superbad premiere is a perfect starting place. The lightweight fabric and short sleeves make it perfect for now — and when the weather cools, just add a turtleneck and tights! Get Kristen’s ruffled Kyumi dress in purple (or blue), $215, at revolveclothing.com, or for a less expensive version, try this one, $68, at urbanoutfitters.com. Finish the look with a pair of nude peep toes like Kristen’s sold out Kenneth Cole ones. Try the “Fatima” by Guess, on sale $51 from $99, at piperlime.com for a similar look.
