Athleta, the Gap’s answer to Lululemon, is heading to Rockville Pike. The activewear store will open next spring at Congressional Plaza, alongside Chico’s and just around the corner from upcoming tenants CorePower Yoga and Orangetheory Fitness. This will be the third Athleta in the D.C. area (the others are in Tysons Corner and Georgetown) and the first activewear store to open at Congressional Plaza since Lucy went out of business in 2017. The athleisure clothing segment has been booming this year, as women working at home spend even more money on stretchy leggings and sports bras. In fact, Athleta’s sales have been racing past those of sister brands Gap, Old Navy and Banana Republic.
