Pedestrians pass luxury fashion stores, including Prada Spa, Giorgio Armani SpA and Ermenegildo Zegna Ltd., on the Diamond Walk promenade at Sandton City Mall in Johannesburg, South Africa, on Monday, July 27, 2015. Prada SpA, Ermenegildo Zegna Group and Jimmy Choo Plc are among international brands that have opened their first Johannesburg outlets on the newly built promenade, an effort to lure wealthy customers to a luxury goods enclave on the world's poorest continent.
