DO: This is a great window display promoting men's leather jackets. The store layered the exact same message three times in a single glance- front window graphics, the mannequin and the large poster behind. This achieves greater impact. Besides, it is always more effective to tell one story at a time. DON'T: The mannequins and graphics on the glass promote back to school clothing. However the large graphics behind the mannequins show a more format approach. --a woman in a tux and a man in a suit, mixed messages anyone?
