Dressed to win or dressed to sin?

From the swankiest red carpet events and movies premieres to the city streets, Hollywood’s hottest stars were dressed to rock and shock this week in the best, worst and wackiest fashions – and RadarOnline.com has all the photos and details about who looked hot and who most certainly did not.

Hot mamas alert! While Kate Hudson flaunted her boobilicious assets in a red hot Prabal Gurung gown at the amfAR Inspiration Gala and Jennifer Garner steamed up a Washington DC screening of Argo in Roberto Cavalli, Britney Spears looked better than she has in years at the City of Hope Gala, wearing a gorgeous, shimmering Halston Heritage gown.

With her pink and purple My Little Pony hair cascading down her shoulders, Christina Aguilera experienced a fashion flop at the American Music Awards nominations, pouring her curves into an unflattering skintight purple number.

Khloe Kardashian also missed the a la mode mark, looking a little too dressy for daytime, wearing a nightclubbing dress for an afternoon stroll around South Beach.

As for wacky, Lady Gaga glammed up in Saint Laurent urban cowgirl duds for the Yoko Ono Grant for Peace Ceremony, while Courtney Love appeared to be wearing a dead ferret around her neck on the streets of NYC.
