Where to sell a new wedding dress on the internet?

I have a new wedding dress with tags, and I am having the hardest time selling it. I tried Craigslist, but all of the replies I got were scams. I don’t think I want to use eBay, because the dress I am selling costs way more than the other dresses for sale.
There are a lot of sites to sell used/new wedding dresses, but there are fees that average $25 to post.
Does anyone know of a good site to sell a new wedding dress?
