>> This season, the quintessential "girl" color gets a much-needed update. Spotted on the Spring 2011 runways of everyone from Costume National to Valentino — and in every shade from barely-there pastels to super-bright magenta — pink is definitely the hue of the season.

Look for pieces with modern, pared-down silhouettes and surprising details: accessories in unpredictable materials; dresses in clean, breezy shapes; and jewelry that walks the line between delicate and tough.
