You probably didn’t get a piece of H&M’s Comme des Garçons line. But you have a better shot at getting a piece of the chain’s next designer collaboration with Matthew Williamson, which includes two shipments, a coveted one-off rarity. Known for mixing bright prints, Williamson’s women’s collection will hit a select 200 stores April 23. A second delivery will hit all 1,700 H&M stores in May and include women’s and menswear. The collaboration marks Williamson’s first foray into men’s clothes. The designer, who recently split from Emilio Pucci to focus on his own label, is opening his first U.S. flagship in the meatpacking district early next year. The announcement of the H&M line is a great way to drum up excitement for his U.S. expansion. Not to mention a great way to get people to buy his clothes in this crappy economic time.
