Cassie knew she could make extra money selling vintage clothing on the internet, so in her first semester out of grad school, she drove to Chulas Fronteras Ropa Usada, down by the border in the maquiladora district. The bouncer at the door weighed Cassie on a scale as a shoplifting precaution, and handed her a ticket, along with a map of the enormous warehouse. She was originally from the border, and so she said “No, thanks” to the map, since she knew her way around well, and walked inside. There were hills of denim, with polyester, wool, and old jeans compacted, forming different roads. Fans as tall as Cassie were blowing everywhere like electric windmills, creating metallic cyclones that howled over the exclamations of people—mostly brown women like her, but many with young children—picking through the used clothing.
