Here are Nickelodeon queens Keke Palmer and Miranda Cosgrove, who both opted to wear dresses with sparkle featuring the color peach. They both look very age-appropriate. Miranda’s in Sass & Bide.

7:15: And let’s not forget Rumer Willis in an emerald-green, mirrored dress — the color goes well with her red hair.
And for those of you wondering, Lo Bosworth is here, and she’s wearing the teal strapless dress. Great choice!

8:25: Miley Cyrus is here in a nude-colored halter dress with a draped neckline and a mini train. Lots of rings keep the look youthful and hip. I have to approve, since it’s Moschino — and who doesn’t love Moschino?
