All of those companies you named are good, but I have also been able to find vintage looking clothes really cheap on Shein. Also other places like Etsy, thrift stores, and Goodwill are good options. Also, I will literally use Google and just put in, for example, 1940s vintage dresses, and it will give me multiple options. You can find different companies that will sell different things. That’s just one way that I’ve been able to find multiple companies and get clothing for different prices.
