There's no shopping component integrated into "Outfit Compare" (yet), but TechCrunch positions this launch as the next step in Amazon's quest to grow beyond a marketplace. While the feature is only available to Prime users as of now, it's not meant for input on clothing or accessories bought exclusively off of the site — rather, it's meant to offer a new type of service to its existing clientele. Simply put, it's "a free service that gives Amazon Prime members a second opinion on what to wear," a company spokesperson explained. Plus, it's a different way to broach the fashion space, a category Amazon has been some time now , building a whole new way to get answers to a question we already ask ourselves on the daily. (It's not a totally new concept in the tech world, though: Tinder Stacks offers a similar capability.)
