At only 16 years-old, Dakota Fanning is quickly evolving into a style icon! While her underage peers are running around scantily clad in scandalous style (ahem, Taylor Momsen!) the Twilight star gets gowned in truly tasteful threads. Case in point. The blonde babe hit the 2010 BAFTA Britannia Awards in Los Angeles on Thursday night, looking absolutely angelic in a Valentino Haute Couture gown from the Fall 2010 collection, which featured a princess-worthy train and a bowed back. House hottie Olivia Wilde also looked fab in her designer duds, wearing a dark and dazzling Michael Kors ensemble.

Dynasty, redux. Joan Collins hit Beverly Hills old favorite Mr. Chow with scribe sis Jackie for dinner, pulling one of her trademark 1980’s sharp-shouldered blazers out of the closet. Though the 77-year-old star looked a tad outdated in the attention-grabber, she surely had Lady Gaga and Rihanna dialing up their stylists!  See Joan’s tacky Dynasty duds here.

Sequins were a hit this week, with Kim Kardashian (in alice + olivia by Stacey Bendet at the NYC opening of DASH), Ashlee Simpson-Wentz (in vintage Chanel at the Decades Denim Launch in L) and Madonna (in a tunic mini and Stella McCartney perforated boots at Fashion Has A Heart in NYC) all scoring Best Dressed nods for their ensemble efforts.

Julianne Moore scored two wins on the wardrobe front, following up her brightly hued Lanvin ensemble at the Rome Film Festival photocall with a dazzling Giorgio Armani one-shouldered gown at the premiere.

And on the Wacky front, Margaret Cho and Johnny Weir were up to her usually tacky antics in disastrous duds, while former supermodel Angie Everhart channeled Anne of Green Gables in Hollywood.
