If you're a city hosting a fashion week and you're not New York, London, Milan or Paris, you need something to make yourself stand out. For Copenhagen, that thing is the longest catwalk in the world. Copenhagen's fashion week, which runs from August 11-15, will culminate with a fashion show on what is being called the "World's Greatest Catwalk." Strøget, the pedestrian street that runs through the center of the city, will be transformed into a mile-long catwalk, down which 220 models will walk. The models will wear designs from over 500 Scandinavian brands. Also the runway will be pink.
