This picture collage has the coolest concept. I love how this image is all black and white and then there is a colour splash on the water in the hula hoop. They have done a very good job editing this image.
Mirror installation / Ron Gilad Or-- Another idea: how about a photo ( inside or outside of your store) with a mirror cut out to reflect face(s). Customers can see themselves in the color/clothing without having to try it on!
