I've reverse searched for this dress, a Y2K prom dress by Cache, but the few that I've found are on thrift websites (depop, Poshmark, etc) and all going for at least $800. Which is crazy high and these used to be considered "fast fashion" type dresses when they first came out. Most all other y2k are also in the $400+ range

Can anyone recommend where to look for Y2K prom/evening dresses? Especially in size small/extra small or in NYC. No luck in physical thrift stores
