Amazon is launching Prime Wardrobe, a new program that will let you try on clothes before you buy them. Once you select at least three Prime Wardrobe-eligible pieces from over a million clothing options, Amazon will ship your selections to you in a resealable return box with a prepaid shipping label.

After you try on the clothes, you can put the ones you don’t want back in the box and leave it at your front door — Prime Wardrobe also comes with free scheduled pickups from UPS. If you decide to keep at least three items you will get a 10 percent discount off your purchase, and if you keep five or more pieces the discount rises to 20 percent.

This is Amazon Fashion’s latest attempt to grow its retail footprint — Amazon launched the Echo Look “style assistant” back in May, and it began working with celebrities like Dwyane Wade to build out mini stores on its website. Given Amazon’s history of entering and methodically dominating retail markets (see: books, electronics, and probably groceries), this likely isn’t the last move we’ll see from Amazon Fashion this year.

Amazon Prime Wardrobe is currently in beta, but you can sign up to get notified when it officially launches.
