Selling my wedding dress

I have a brand new wedding dress that I never wore. I'm still making payments on it, and money's tight right now.

I've tried selling it on Craigslist and on those online yard sales that are on facebook.

It's a $1000 dress, and I only want to get about $450 to finish paying it off. But nobody will buy it! It's a gorgeous dress, but gosh it's hard to sell. Lol

I don't want to pay to list the dress on a website.. so any ideas on where else to try to sell it?
