PHOTOS: Celebs In The Best, Worst & Wackiest Fashions Of The Week

From London Fashion Week to Wall Street, stars hit the scene in fab fashion and absolutely arrest-worthy attire this week.

Sarah Jessica Parker lived up to her style icon status at the Burberry Prorsum Spring 2011 runway show in London, wearing a leather peacoat with a lace miniskirt from the Brit brand, while carrying a glittery pink Alexander McQueen purse. Tres Sexy!

While platforms boots are a super hot trend this fall, not everyone gets the look right---take it from Lenny Kravtiz! The hippy rocker hit the streets of NYC wearing a pair of the boots of the season with leather pants and a cowl-necked top, while carrying a purse. Now that's what we call feminine fashion.

Gisele Bundchen was on a style streak this week, looking supermodel sophisticated in a cream jacquard cocktail dress and nude Christian Louboutin pumps at the Dinner For Important Women in NYC. A few days later she showed up to the Brazil Gala at the MET, showing off her flawless figure in a custom-designed Calvin Klein sequin gown.

Kate Moss and Amber Rose committed fashion fur-pas in London, while Paz de la Huerta went a little too wild at the New Yorkers for Children Fall Gala
