I would try Greene Street or Poshmark for workwear. Buffalo exchange is much more casual/vintage.
Yes they're very hipster trendy but if you have the right stuff they will pay you for it before my Nike Air Maxes for $37 they bought Versace khakis for about 12 so they really want more patterns jeans and cool sneakers oh and no by backpacks
They don't take suits. If anything is out of style they won't take it. The only old stuff they may take is vintage items.
They may if the items are new and in style the older and more out of style the less interested they are going to be also they only pay peanuts so get ready to be instituted with their offer
You can call and ask, they will give better info if you bring it in for them to judge. They are very nice.
