Milan

In addition to the Town House Galleria, the world's first seven-star hotel, Milan offers the Armani, named after you-know-who. Don't forget your debit card when you hit the Quadrilatero d'Oro (the Golden Quad) for Armani (the store, not the hotel), Dolce & Gabbana, Prada, Valentino, Gucci and Versace. Here, Versace alone is spread across four floors. Second-hand shoppers should head to the Navigli neighbourhood, Milan's own little Venice complete with a grand canal, as well as fashion treasure troves Eliogabaldo, Biffi and Floreta Coen Musil.
