Consumers in the United States and the United Kingdom enjoy some of the world’s most generous merchandise return policies. It is no wonder, perhaps, that a few shoppers presumably buy clothes and return them afterward, no questions asked. Some people may be tempted to wear, post photos on Instagram, and then return the clothes. Is this so-called renting, or wardrobing, wrong? Italian clothing brand Diesel created an ad campaign dubbed “Enjoy Before Returning,” poking fun at the practice by showing young people wearing the company’s duds with tags still attached. Why might Diesel be mocking wardrobing? Do retailers invite such behavior with their liberal policies?
