As we strive to shop smarter and consider the negative effects of fast fashion, the vintage market has quickly become a go-to source for many buyers looking to invest in unique, one-of-a-kind pieces. As consumers increasingly become more aware of their buying power and are tracking exactly where their money is going, the secondhand market is looking particularly appealing — not just for the often marked down prices, but for style, quality, and recyclability, too. As popular as Etsy has become over the past few years, many consumers still don't understand the monstrosity of the marketplace that it is. So, instead of you doing the heavy lifting and sifting through the shops, we've taken it upon ourselves to source the best vintage fashion destinations that we could find. Scroll down to shop away.
