Where to sell wedding dress?

Fiancé passed away a while ago and I have my wedding dress that serves me no purpose and is a bitter reminder just sitting in my closet. I have it posted on Facebook, Craigslist, instagram and Poshmark (seem to get a lot of scam replies there). Is there anywhere else I am missing to post? I know I will probably have no luck as new brides want to buy from the store to have that “magical moment”, I get it. I originally paid 2098, but am asking 900. My dress is brand new with the tags still attached and unaltered. It really is pretty, but again, serves me zero purpose and quite frankly don’t see marriage in the future ever happening for me.

Edit, the shop won’t take back the dress, said all sales are final, which I think is crappy for my situation.
