Alicia Silverstone in a little black dress
Alicia Silverstone pauses for a photo in what appears to be a little black dress on December 14, 2006. This was at the St. Regis Resort Monarch Beach in Dana Point, California, which was hosting something called a "Chateau M" party.
(We just looked it up: Per The Orange County Register, this was "the annual bash hosted by Paul Makarechian, whose family owns the St. Regis Monarch Beach Resort and Spa... Each year, Makarechian’s party has a different theme. Last year was 'Studio 54,' as in the ’70s disco. This year was 'Chateau M,' inspired by the French Riviera, the glitz of Monaco, the glamour of the Cannes Film Festival." Got it!)
