I'm late to the party. I just watched "Frozen" about a month ago. I think it's a great movie. It's still not my favorite, but I liked it a lot. (Toy Story is my fave, Belle is my favorite princess.)
That being said, I don't actually want to look like Belle at my wedding. Why? Because I'm an adult. Granted, I'm an old adult, but if my daughter wanted to be Elsa for her wedding, we would have to have a serious talk about her being mature enough to get married.
Alfred Angelo has a new Cinderella line of wedding gowns. More power to them, it's great publicity. I'm just not really into the whole colored wedding gown thing -- though if I had to have one, it would probably be Lilly. : )
