We had the Cinderella dinner at 1900 Park Fare in June and saw the cutest thing ever - a little girl dressed as Cinderella but it was Cinderella in her "before" dress, as in before the fairy godmother came. It was a very simple skirt with a ragged hem line and matching top and a little brown kerchief on her head. She looked like she was ready to scrub the palace floors! Honestly, it was the cutest thing, and so original! I'm sure she was also much more comfortable than a lot of the girls in their princess dresses, especially if she had been in the parks prior to dinner.
Anyway, I loved seeing all the little princesses. If my dd, now almost 17, were little again you can be we'd be doing the whole "dress up for the princesses" thing. Actually, she'd do it now if she could find one to fit!
