Recently making her way back overseas, Mischa Barton was spotted partying the night away in St. Tropez, France on Thursday (July 8).

Clad in a questionably colorful, skull-printed maxi dress, the former "OC" star hit the club scene after attending the Philipp Plein store opening in the riviera locale.

As for the reason behind her appearance, Miss Barton happens to be featured in the label's Autumn/Winter 2010 ad campaign.

The fashionable endeavors come as Mischa continues to struggle in the entertainment business, with her most recent show "The Beautiful Life" being chopped after a few episodes.
