I believe Wag stands for "Wives and girlfriends," but it's hard to keep up these days. Wags Boutique is a new show where girls compete to run the most successful clothing boutique in the heart of fashionable Soho. These are just a couple of the non-traditional executions that are being used to advertise the show. The Chihuahua urinal is hilariously brilliant. Nice work by M&C Saatchi.
