NSFW: Looking at maybe selling used underwear. Is this doable? What are the how-to's? What do guys who buy them like?

I apologize if this isn't appropriate for the sub, so be nice please lol.Title says it all. There's info for girls everywhere, but I can't find anything for guys. I'm poor and need money the next few months. Looking to make a quick buck on the side. I've never done anything likes this before. I have a lot of old underwear (boxer briefs) that have holes in them.Is this a viable thing? Where can I go to learn more? Prices? What should I do to my underwear to make them more valuable? Would women buy them too (might as well)?EDIT: OK, socks or other clothes too.
