"I'm pretty blown away... It's a toy in the dressing room. It enhances the experience"

"Imagine a fitting room with a "smart" mirror that suggests jeans to go with the red shirt you brought in."

Stores are tapping into the significant role the often-forgotten fitting room can play in purchase decisions. While 36 percent of store browsers wind up buying something, 71 percent of shoppers who try on clothes in the fitting room become buyers, according, Paco Underhill, a retail consultant. Yet the typical fitting room isn't always inviting: Only about 28 percent of shoppers even walk into a dressing room of a typical clothing chain, Underhill says.

"The dressing room experience in many places has been close to miserable," Underhill said. "There's bad lighting. They're dirty. And they have poor service."
