Wasting no time since winning the 2010 Swarovski Menswear Designer of the Year award, Richard Chai is set to unveil his first retail outlet, albeit a temporary art installation. In a series conceived by Building Fashion, Chai enlisted (the cleverly named) architecture firm Snarkitecture to create a pop-up store carved from a single piece of foam-like material beneath the High Line. Visitors are enveloped in an eerie glacial cavern as they peruse both the men’s and women’s collections. The Richard Chai Store, 504 West 24th Street, October 21-31, 12-6 pm.
