Fashion retailer H&M opened the doors to its largest store in the world on Fifth Avenue, New York City last week.

The Swedish business unveiled the 57,000 sq ft store on July 17. The launch saw artist Jeff Koons take over the store for the day, with the six-story façade featuring one of his famous balloon dogs.

Koons also collaborated with H&M on a limited edition balloon dog handbag that was available at the shop.

The store carries every product the retailer makes and it includes a shoe lounge.
