'Matthew Williamson For H&M' Launching Party

The night before it's public opening, many Matthew's celebrity friends had been invited to attend the pre-launch party for early shopping from his price-friendly line.

What do we love, we mean really really love about this Matthew collection for H&M? It's the resemblance with his real collections for Matthew Williamson, but with much more affordable price of course!
