There is no "shop window" anymore. In the old days, there were shop fronts that had mannequins that had to be dressed up every day or at least once a week.
Now, printing technology allows us to have a large screen in vinyl that has life-size pictures of men and women in just the clothes we aspire for. Lighting technology now allows this screen to have a special accent and to highlight that which must attract us, most hurried customers.
In Bombay, in the 80's, Benzer, the super store happened, at Warden road, which was by then, renamed Bhulabhai Desai road. It was the place to go to shop. There were no malls then. Benzer had a "shop window" It also had a small "landscaped" area at the entrance with sculptural blocks clad in granite stone.
There was an outside to the store and an inside. You stepped in to see what was possible, at what price. Today, in the mall, you often see the whole store from the outside. All the T-shirts racks, all the discounts being offered... It is like having a walk-in closet.
