Love this dress. Placed the time period right away.
My sister also wants this dress in white for her wedding.
Also, on the "historical accuracy loop-hole abuse," I personally love the fairy godmother excuse for Disney Princesses. Between Aurora being raised in the woods by three fairies who know next to nothing about human lives, and Cinderella having a very... er... absent-minded fairy godmother, you always get a little wiggle room. xD (Still think this was the best choice you could have made, though.)
