Georgia May Jagger and Kate Moss at Longchamp’s Regent Street flagship opening. (Can’t you relate to Georgia May’s grin?) All photos by Dave Benett/Longchamp.

Store opening parties can be hit or miss—the lights must blaze in order to highlight the merch on display, and champagne flutes rest uneasily near displays of luxe leather clutches. But last night’s party to fete the opening of Longchamp’s Regent Street flagship was a hit of the hautest variety. Kate Moss was there. So was Mick Jagger. Alexa Chung and Pixie Geldof shared spinning duties.

I applied Cher’s party strategy from Clueless—"Let’s do a lap before we commit to a location"—eventually settling near the DJ booth. Rihanna’s "Only Girl in the World" got the crowd lip syncing along, but it wasn’t until Icona Pop’s "I Love It" came on that the dancing started.
