We like to shake things up here in Style Superstar land. Sometimes, we honor celebs with consistently killer style, like Emma Watson and Nina Dobrev. Other times, we recognize stars who burst onto our radar after sporting a fabulous outfit, like Rosie Huntington-Whiteley or Rosa Byrne. This week, we’re rewarding one of young Hollywood’s finest celebs for pulling a phenomenal fashion 180: teen queen Miley Cyrus.

Miley’s made headlines for some very revealing outfits on her recent world tour, but she emerged at a benefit for the Starkey Hearing Foundation in Minnesota this week wearing a stunning, sophisticated and, yes, very sexy black dress. The asymmetrical, one-sleeved gown fits her rockin’ bod like a glove. It’s mature, but with hot orange nails, subtle bikini top tan lines and undone hair, Miley doesn’t look like she’s trying too hard to grow up. A lesson we can all learn from Ms. Cyrus? You don’t need to have your cleavage, midriff and legs on display in order to be sexy! We hope this sleek, understated sex appeal continues in her future red carpet appearances.

Fellow former Disney star Demi Lovato has also been slowly making her way back into the spotlight. During a stop at Y100 in Miami to promote her powerful new single, "Skyscraper," she opted for a heavily accessorized, loose-fitting outfit. There’s no doubt that Demi’s a stylish chick; she’s wearing some super-hot trends, like hair feathers and ripped jeans. Altogether, though, the hat and bangles and slashed shorts and cross necklace and peep-toe heels are just too much. Demi does look gorgeous (and happy!), but she could look even better if she downplayed the accessories and wore either a more fitted top or more flattering bottoms.
