Yes! This is why ASOS changed their return policies to be able to 'blacklist' people who serially return things.Wardrobing is a form of return fraud where an item is purchased, used, and then returned it to the store for a refund.
(Just going to quote the below article)
"The rising trend of ‘wardrobing’ is fast becoming one of the biggest challenges facing the retail industry, and it’s not just limited to apparel. A report from Brightpearl showed that 40% of retailers have seen wardrobing increase, and 44% agreed that their margins are being strongly impacted by handling and packaging returns. Furthermore, 70% revealed their business profits will be “further squeezed” as try-before-you-buy (TBYB) becomes more popular."
Not saying shes a bad person and millions of people do it worldwide .. but its just definitely not done without consequences for a business.
I work in e-commerce (though for quite a small company) and don't think people appreciate that even if postage is free for the customer it's not free for the business and the costs of 2 lots of postage (both to send an item and the 'free' return) really add up. Not to mention things returned in an unsaleable condition.
