How exactly a shirt covered in swastikas made it through the design process, much less crammed into a rack in a Ross Dress for Less store in Florida where Bloomberg found it this week, can probably be chalked up to retailers’ vast and complex retail supply chains, where errors can often go overlooked.

The shirt had been designed by a company that licensed the Airwalk brand, then manufactured in India, shipped to a U.S. warehouse, and delivered to Ross stores, according to people involved in the process. Apparently nobody flagged it along the way. Ross Stores Inc., a discount clothing chain with more than 1,500 stores across the U.S., said in a statement that it was removing the shirt from stores.
