Where are you guys taking your old dresses?

Mine has had absolutely no luck on standard listing places like stillwhite. It was like 6K new and unfortunately the wedding didn’t happen, so I never want to wear it because it was for a guy who is no longer in my life. Bought myself a cheaper gorgeous dress for my current fiance.

I’ve listed it for like 2K. I’d love to get some money back to give back to my mom, but I’m also considering just donating it. I’m open to any suggestions. Thanks. I’ll post a picture if allowed but I’m not sure if I am.
