Another designer got the memo on the crossover between ready-to-wear and performance apparel (aka sports gear or workout clothing). Alexander Wang introduced his new collaboration with H&M the other night and, POW, he hit a home run with athletic-inspired looks made of performance fabrics so they can go to the gym and the office. For several years I’ve noticed more and more women wearing brands like Lululemon as ready-to-wear–oh those yoga pants! Luxury brands like Hermès and designers like Tory Burch picked up on the trend and launched — or are launching — their own lines of sporting apparel. Even Haute Couture houses like Dior and Chanel started selling very expensive sneakers. I’m sure Wang’s looks for H&M will fly off the shelves when they arrive in store on November 6th.
