Housed prominently in Baccarat's former space, Cop.Copine officially opens today in Union Square. The Parisian fashion label is looking to bring a taste of French Bohemian style to San Francisco with their beautifully draped dresses, cutting-edge fabrics, a youthful edge and of course, a certain je ne sais quoi. With their grand opening party (celebrating Jennifer Siebel Newsom) still over a month away, you have just enough time to assemble the perfect ensemble for what's sure to be an affair to remember.
