Amazon.com launched on Tuesday a subscription-based box shopping service, Prime Wardrobe, as the online retailer steps up efforts to boost its apparel business.

Prime Wardrobe will allow Amazon Prime subscribers to choose and try clothes, shoes and accessories from brands including Calvin Klein, Hugo Boss, Adidas, Levi's, as well as Amazon's private labels.

The service is similar to a number of "try-before-you-buy" services including Stitch Fix, TrunkClub and Rent the Runway.

Customers will be charged for the items they decide to keep and will get higher discounts if they buy a larger number of items, according to Amazon.

After they try on the clothes, customers can put the ones they don't want back in the box and leave it at their front door - Prime Wardrobe also comes with free scheduled pickups from UPS.

Amazon Prime Wardrobe is currently in beta.
