For me at least the thing is, I wouldn't pay that much money (if I HAD that much money..) for something that's already associated with someone else. It will forever be a "Carrie" dress and to be frank if I was getting married, I'd want a "me" dress (albeilt a Vivienne Westwood "me" dress;)). And another thing? I mean, she didn't even get married in the dress. The whole thing turned into a disaster.. so it's not a very lucky dress, is it?
But it is quite lovely non the less (althou I prefer the longer version). Here's a link to the net-a-porter site, where you can buy it for a small fortune: http://www.net-a-porter.com/product/41379
