Luxury retailer Polo Ralph Lauren is taking its 'window shopping' experience to its Michigan Avenue flagship store in Chicago, allowing customers to shop from outside the store 24 hours a day.

The new display is themed around Aspen's ski slopes and, as well as allowing shoppers to buy goods from the RLX line of apparel, also provides ski tips, live weather and ski conditions, interactive trail maps and style advice for various ski conditions.

Shoppers interact using a touch screen, which is powered by a transparent foil applied directly to the glass.

The latest installation follows an interactive window at the company's Madison Avenue store in Manhattan, which was designed around the US Open tennis tournament.

"This is an incredible and dynamic way for customers to experience the advanced precision of the RLX line," said David Lauren, senior VP advertising, marketing and corporate communications at Polo Ralph Lauren.
