Amazon wants to turn your home into a fitting room.  Today, Amazon introduced Prime Wardrobe, a new service that lets Prime members try on clothing and accessories before buying them.

Here’s how it works: Choose three or more items to put in your Prime Wardrobe box, such as clothing, shoes or accessories. Try them on at home and you’ll have seven days to decide which ones you’ll keep. Then, return any unwanted items at a UPS location or schedule a free pick-up.

Members will get a 10% discount if they keep three or four items, or 20% off if they keep five items or more.

Amazon said members can select from over a million items across its women, men, kids and baby departments. There is no additional fee for using the service.

Prime Wardrobe is currently being beta tested. Amazon declined to share when the service will launch.

Other companies, such as and BlackCart in Canada, offer similar services where customers can try on clothing before buying. Meanwhile, startups Stitch Fix and Le Tote send customers curated items they can try on and return.

Prime Wardrobe is Amazon’s latest foray into fashion. In late April, the company unveiled the Echo Look, a device with a voice-controlled camera that takes full-body photos and videos of your outfits.

An accompanying app keeps track of different outfits in a “personal lookbook” and its “Style Check” feature lets you select two photos and have Alexa decide which one is better.

Amazon continues to pursue different markets, such as fashion and food. Last week, Amazon said it would buy Whole Foods for $13.7 billion.
