Where can I find a good replica of Belle's, from Beauty and the Beasts, dress?

Either her casual or her fancy one would work. I need the whole outfit and I don't really care about the price, I have a while to save up for it. Any help would be nice! Thank you!|||disneyland? ebay? something like that... going trick or treating early? ;)|||It depends what you want it for, if you're after a cheap version then the fancy dress option below might be useful for you.
