thrift store chic
When you go into a Neiman Marcus, Nordstrom or Marc Jacobs and there are $50 tank tops stretched and faded, and generally looking like they came out of a pile of salvation army clothes. you are think WTF? but other people are eagerly trying them on and buying them, even though if you were to suggest they go to an actual thrift store and get the same clothes for $1.99, they would be shocked/horrified/appalled.
That $200 faded black hoodie with the intentional silver paint splotches is so thrift store chic.
