Prom/Special event gown

This is the most beautiful gown it's covered in jewels and sequins. It's Navy blue with silver jewels . This gown is a size 10 and unaltered. I'm truly sad I will not be able to wear this dress as my event has been cancelled due to the coronavirus. So I'm looking to get some of my money back since the store will not take it back 😕. I paid $500 and I'm open to serious offers .
