Concrete Jungle is a pop-up shop selling casual urban clothing and accessories. Primarily carrying graphic T-shirts and hoodies, the featured designer is Annie Mulz, which is not a single individual but a playoff on the word "animals." The brand's overall concept is a whimsical embodiment of "natural law," represented by a teddy-bear silhouette caught in the cross hairs. Other brands include George Guest, Born to Purple and the Collective. Concrete Jungle will only be on Newbury Street for a limited time, but its items can be purchased online.
