One of the major drawbacks to shopping for clothes online is the uncertainty of whether or not what you buy will fit once it arrives at your home. Amazon Prime Wardrobe is an attempt at lowering that stress for Prime Members.

Amazon has created a service that allows members to pack a box with up to 8 items of clothing. They then have a week to try them on before being charged for any items they choose to keep. This is Amazon’s offering to compete with popular personalized shopping services like Trunk and Stitch Fix.

One main difference in the Amazon process is that the customer is tasked with selecting from a curated ecosystem of clothing which is presented in Prime Wardrobe. Companies that are available to choose from include: Nine West, Disney, Stuart Weitzman, Gymboree and many more. Amazon’s private label lines are also available in the program.

The service which has been in beta over the past year is now available to all Prime members in the U.S.
