Lululemon and Lucy just got some fresh competition in the D.C. market: Chelsea Collective, a female-focused subsidiary of Dick’s Sporting Goods, opened its very first store this month at Tysons Corner Center. The merchandise is a mix of clothes, shoes and fitness accessories from mainstream brands like Nike and Under Armour as well as trendier lines like Zobha, Splendid, Lorna Jane, Spiritual Gangster and the new Calia by Carrie Underwood. The store aims to please with tailoring services a la Lululemon, gait analysis a la your favorite running store, and a “girlfriend lounge” equipped with treadmills and ballet barres to test the merchandise in action.
