Even if Unknown Union had nothing inside, we’d still class it as a must-go, featuring as it does the best designed concept stores in Cape Town. For while its range of men’s apparel is undeniably trendy, it is the shop’s interiors that really turn us on; conceived by New York-based architect/interior designer Rafael de Cárdenas from Architecture at Large, the two-tiered space features luminous stacked-box shelving offset by stark white walls. On the second floor is an ever-changing creative space where artists can showcase their work. Indeed, if this store doesn’t encourage you to punish the plastic, we don’t know what will.
