This Week's Fab Five

Posted by babu 3:43pm GMT

This week was all about keeping it classy. And the winners are...

Michelle Trachtenberg in Marchesa at the 2011 School Of American Ballet Winter Ball. The actress, who has undergone a complete style transformation lately, looked romantic in this whimsical chiffon gown, which reminds me of something Taylor Swift would wear.

Selena Gomez in Dolce & Gabbana at the 2011 Disney Kids & Family Upfront. I love when Selena wears red, because it really works well with her dark features. In this case, she upped the ante with matching lips and red bow-clad heels for salsa-fying results.

Kelly Rutherford in a steel-hued, silk gown at the 2011 School Of American Ballet Winter Ball. The "Gossip Girl" star exuded head-to-toe glamour in this asymmetrical gown, which featured beautiful beading along one shoulder.

Thandie Newton in a Marni dress and coat at the Birds Eye View Film Festival in London. Thandie looked polished to perfection in this prairie dress, coat and boot pairing. She topped off her sophisticated, yet sexy, ensemble with a chic handheld bag.

Celine Dion in Armani Prive while performing at The Colosseum at Caesars Palace. Celine looked nothing short of enchanting in this fairy-tale-esque gown, which was dripping with sequins and featured a fresh cutout in front.

Which star's classy style is your fave?
