The Ten Best Dressed of 2007 Classic or continental, girl-next-door or vamp, each of these women made all the right fashion moves. By Melissa Liebling-Goldberg THE SHOWSTOPPER Beyonce Knowles never misses a beat, whether she's glam on the red carpet in Versace or street chic in white jeans and a yellow jacket. THE LEGS Cameron Diaz shows off her gorgeous gams whenever possible – in minidresses like this peach Chanel or in skinny jeans like her favorite 7 for all Mankind. THE CLASSIC From her chic bob to her enviable accessories, Katie Holmes has locked down the refined look. She sizzles on the red carpet in a flawless Azzedine Alaia frock and is a hot mama in wide Roland Mouret trousers. THE CONTINENTAL Penelope Cruz embraces fashion in a big way, from slinky Versace gowns on the red carpet to immaculate Dior dresses on the streets of Paris. THE ALL-AMERICAN Jessica Biel knows what flatters her athletic figure – strong colors, like her fuchsia Oscar de la Renta gown at the Oscars, and simple cuts, like her white Hudson jeans on the streets of N.Y.C.
