Wedding Dresses

I have a brand new wedding dress that I bought last year from David's Bridal and I am trying to sell it. My fiance & I pushed our wedding date back and by that time I will have saved enough for the dress I realllyyy want. So if anyone knows anybody or any site where I could most likely salevit please comment! Its brand new, never worn (other than trying on in store), white, strapless, long train, size 22. I will try to post pics soon.
