Giorgio Armani celebrated 40 years in fashion last night in exactly the way you’d expect: with a crazy party, couture show, and opening of his very own museum in Milan. The eventful evening began with a tour of the new Armani/Silos, a museum and exhibition space encompassing 4,500 square meters and four floors dedicated to Armani’s career. The debut exhibition, which opens to the public this month, showcases 800 outfits and 200 accessories.
