Tiffany & Co.unveiled its interactive installation, "Fifth & 57th" at Old Selfridges Hotel — a re-creation of the subway train stop that alights at the American jeweller's flagship store in New York City — to celebrate the new Tiffany store in Selfridges London.

Attending the 300-strong event were Poppy Delevingne, Caroline Issa, Olivia Inge, Zara Martin and Graham Norton. Guests were greeted by a cocktail reception, and images of Manhattan were projected on the walls to transport everyone to the city that never sleeps, the home of the New York minute.
