Even while we're fully immersed in the Fall '11 collections, the beginning of March has me thinking all things Spring. I've been eying the past Spring '11 runways and the brights they brought in the form of these flirty frocks from Versace, Matthew Williamson, Peter Som, and so many others. This is a different kind of LBD necessity, so forget the little black dress and allow me to introduce this season's must-own little bright dress. The colorful options are limitless, as are cuts and silhouettes, though we recommend keeping it short and sweet to soak up the sun. Just shop my picks to get the look.Left to right: Versace, Peter Som (middle two), Matthew Williamson.
