Lululemon Athletica and trendy Korean retailer Aland are heading to Williamsburg’s up-and-coming North 6th Street. The athleisure shop signed a lease for 3,450 square feet at 129 North 6th Street, where the asking rent was $205 per square foot, the New York Post reported. Lululemon will join upscale neighbors like Madewell and Rituals when it opens in the spring.
