Don't sleep on vintage, thrift stores, and markets. Believe it or not, there are people out there who don't realize the value of what they're selling. You might just find vintage designer jewelry at your local thrift store or weekend market for a fraction of the price at consignment stores or online. The only downfall is that it'll be harder to make sure the piece is authentic. So to repeat: do your research before shopping at these places. But then again, so what if you spend $4 on a fake Versace chain?
