An idea… buying and selling solo dresses

I am working on an idea designed to help when buying and selling solo dresses.

I know, I know, there are A LOT of dress selling sites, but I have not found anything where a buyer could list what they are looking for so that a seller search easily and then could contact the buyer.

If such a site existed, would you, as a buyer post what you are looking for, OR, as a seller, appreciate the fact that they could search a wish list to hopefully find a buyer faster? Oh, and did I mention listing and searching would be FREE.

There is more to it than that, but just wondering if the base idea has any merit/

Thoughts and opinions appreciated. Thanks in advance!
