This particular dress struck my eye in a magazine ad not too long ago, and I haven't been able to get it out of my head since:

(A/W 08, model is Natasha Poly)
I was stalking the Neiman Marcus website, and the dress is available for online order! And there's only one size in stock - a 34/4 - which would probably fit with minimal tailoring.
Best of all, the dress is a mere $4,975.00
Can I borrow a few bucks?
