Mischa Barton was one of the many stars that attended Matthew Williamson boutique opening party in New York during Fashion Week.

It wasn’t a surprise to see the sometime actress, sometime model, sometime designer, at this event, as she has long been faithful to Matthew Williamson, and often seen in his clothes.

For his special night she opted for a Mosaic sequined dress.

This bedazzling mosaic sequin sheath dress will make you a modern day flapper girl, if you pair it with a metallic t-bar heels, and long beads. You can buy it from Net-A-Porter’s international site £1,463/€1,875.
