Where’s the best place to BUY good, secondhand winter clothes?

Hi everyone! I’ve recently lost a good deal of weight and have sold my good stuff. Any recommendations on places I could get a high quality secondhand coat? I’d rather not spend over $300 for one if I’m going to size out of it, but I’m getting pretty cold and looking silly in what I have. Hoping to avoid online marketplaces.

Edit: Forgot to add - I’m a guy! Thanks for all the recommendations!
