Amazon has expanded Prime Wardrobe to all Prime members, after beta-testing the service on an invitation-only basis for a year. Prime Wardrobe is included in Amazon Prime memberships at no additional charge. “This is going to be an immensely valuable service for Amazon which will increase consumers’ confidence in buying apparel from the company,” said Nikki Baird, VP for retail innovation at Aptos. It appears that private label brands have been the top sellers through the service, but Prime Wardrobe also offers items from some major brands.
