Next H&M Designer Matthew Williamson

Matthew Williamson the British designer best known for his bright, kaleidoscopic hues and equally vibrant patterns and prints will be partnering up with H&M to create a designer collaboration for both women & men. Williamson is often referred to as the designer who never met a color he didn't like. He currently designs his own namesake label as well as sits as creative director at Pucci.

Unlike previous H&M collections, this one is set to roll out in two waves. WWD reports that the "exclusive" women's range is set to hit the top 200 stores in April 23, 2009 to be followed by another range for women and men in mid-May, 2009 in all 1700 stores.

Here's a look at his Spring 2009 runway collection for a taste of what's in store.
