Herrera Shirt Wedding Dress Wanted!

Hi again ladies,
Just to clarify, I really want the pink/white stripe shirt wedding dress that Caroline Herrera makes. I am not willing to pay the retail price, but I am willing to wear a used dress and pay accordingly. I am 5`10 so I would love if it wasn`t hemmed too much and between a size 10-12. I could try and squeeze into an 8 by my wedding 6-6-09.
Thanks everyone!! Any knock-offs of this dress to look at would be appreciated as well!
