More Amazon competition for retailers: 'Try before you buy' Wardrobe

June 20 (UPI) -- Amazon announced Tuesday it is testing a new service called Prime Wardrobe that allows customers to try on clothes before purchasing them.

On Friday, the online retailer it disrupted the grocery industry by announcing it will acquire Whole Foods for $13.7 billion.

Prime Wardrobe is part of Amazon Fashion and is being being tested in beta, Amazon said on its website. Customers can receive an email when the service is launched.

The website boasts the following advantages: "try before you buy," "you get to choose" and "free, easy returns."

Prime Wardrobe will include brands outside of Amazon's private labels, including Adidas, Calvin Klein, Levi's and Hugo Boss.

"Prime Wardrobe is a new service that brings the fitting room to you, so you can try the latest styles and find your perfect fit before you buy," Amazon said.

The service is similar to other wardrobe subscription services like Stitch Fix and Trunk Club.

"Amazon's taking a page from players such as Stitch Fix, which has been gaining steam and grew revenues to $730 million last year by letting users try on looks at home," Evercore ISI analyst Omar Saad wrote in an email to clients Tuesday.

"While Stitch Fix uses a combination of artificial intelligence and full-time stylists to recommend looks tailored for each user, Amazon brings to the table its massive scale, logistics expertise, aggressive stance and nearly endless supply of funds."

Amazon's service will soon be included with all Prime memberships, which include free shipping.

In the system, customers order items that include shoes, clothes or accessories with no upfront charge. They only pay what they decide to keep. Shoppers have seven days to decide what they don't want.

The shipments will come in a resealable box with a prepaid label.

Customer keeping five or more items will receive 20 percent off those items, Amazon said. Keeping three or four fashion items earn a 10 percent discount.

Brick-and-mortar retailers, including Sears and Walmart, have lost business to the online retailer, which is worth $139.3 billion -- the fourth most valuable brand in the world, according to WPP and Kantar Millward Brown earlier this month. Amazon was founded on July 5, 1994 by Jeff Bezos.

The new service will put put pressure on the high-end fashion stores, including Macy's and Nordstrom.
