Mischa Barton wears her pearl and crystal headband, Diesel dress and her leather bag.

A little over three months ago we’ve posted that Mischa Barton will be launching a headband line for Stacey Lapidus. The headband line “consists of six pieces for holiday decorated with pearls, beads, crystals, sequins and flowers. One standout is a silk, crystal and pearl upside-down tiara intended to be worn on the forehead. Priced from $80 to $200, the Barton pieces initially will be sold at staceylapidus.com.”

It will also be the third season for the handbag collection she designed for London-based Ri2k, which is sold in England and Australia. “For fall ’09, Barton plans to work a Seventies vibe.” via WWD
