World's most expensive shopping streets and what Adidas, Chanel and Moncler need to sell there

London - New York City has long been seen as one of the most expensive cities in the world to live in. Therefore it should come as little surprise that Manhattan's Upper 5th Avenue continue to lead the way as the world's most expensive shopping street. The street has managed to hold onto its reigning title for the third year running in the 28th edition of Cushman & Wakefield's global flagship report Main Streets Across the World, commanding an average annual rent of 3,000 dollars per square foot (2,408 pounds). However, unlike last year's results, which saw nearly all of the world’s shopping streets increase in rent, this year saw nearly every high street across the globe decrease its rent, reflecting the turbulent times faced by retailers. For example, rents on Upper 5th Avenue commanded 3,500 dollars (2,303 pounds) per square foot in 2015 - 500 dollars more than this year - which is equal to a 14 percent decrease.
