You wear it, you own it.

Tired of customers returning used clothing, Bloomingdale's has begun attaching chunky, 3-inch black plastic tags to dresses costing more than $150 and leaving them on after their sale.

The special "b-tags," as they are called, are attached to visible places like the front bottom hemline to make them difficult to hide when the item is worn. Once the black plastic tag is removed, the garment cannot be returned.

Bloomingdale's is using the tags to help crack down on a practice so common it has its own name: wardrobing. That's when someone purchases a clothing item, wears it out once or twice—like to a party—and then returns it to the store.
