Style.me’s personalized avatars come courtesy of a web site plugin that adds 3-D virtual fitting room and size recommendations to e-commerce sites, such as that of luxe ath- leisure brand Pam & Gela, a recent retail partner. Customers submit body measurements, and the system checks them against real-world apparel sizes to depict what the garment would look like when worn. People can mix and match up to three items at once in their “fitting room.”
