Amazon offers glamcheck-and a spy's eye

CHARLOTTE, North Carolina - If Amazon's new Echo Look, a service that promises in-your-bedroom wardrobe analysis via an internet-connected camera, doesn't seem unsettling to you, a professor at the University of North Carolina may convince you otherwise.

In April, Amazon unveiled the $200 Look (currently available "exclusively by invitation"). The device is designed for fashion selfies and wardrobe help.

With the accompanying app, called Style Check, you can take not only snapshots but also videos of yourself twirling in your favorite skinny jeans or frowning over belly bloat.
