Vintage stuff I could look for online? (etsy)?

Other than etsy I have no idea of other places to look, but whenever I'm on there I always look for vintage fabrics, that is, if you're into embroidering and sewing, that kind of thing. Sometimes I look for jewelry or accessories (like headbands, earrings, and that kind of thing). Or, you could look at the most popular searches to see what other people are looking for. Hope that I helped! :)
