Things got pretty crowded, pretty quickly at Sandro's cocktail party last night for the French boutique's new collaboration with Dree Hemingway. Guests such as Rose Byrne, Harley Viera Newton, Derek Blasberg and Gilles Bensimon piled in the Bleecker Street boutique, while DJ's Noemi and Benjamin Moreau bobbed in the background and Bellevedere handed out some lethal vodka cocktails. "I'm a huge fan of Sandro from London. Now they're next to Maje and APC's down the street...it's a deadly street, can't come here with too much time on my hands!" joked Bridesmaid's Byrne. Later in the night, the party moved to another French import—Le Baron—for some after-hours dancing.
