If you haven’t heard by now, fast fashion is out, and thrifting is in. People are turning to thrift stores and resale sites like Poshmark in droves. And it’s not just a fluke. According to thredUp’s 2023 resale report, by 2027, the second-hand market is projected to reach $350 billion, with the U.S. at $70 billion alone. And who else would be behind the trend other than Gen Z? The report reveals that 83 percent of Gen Z already thrifts—or is open to doing so. While thrifting in person is fun, doing it online opens up a treasure trove of options for goods of all kinds. Poshmark is a one-stop shop for fashion, home goods and electronics—but what if you wanted designer pieces, vintage accessories, pet supplies or an emphasis on menswear?
