If your daughter is into it and you DON'T bring her dress, she will be really miffed! There's nothing like a little girl seeing all of the other little girls dressed up and SHE doesn't have her dress. If you have one, definitely bring it! Also, bring a change of clothes. Immediately after our dinner at Park Faire, our DD3 wanted that dress OFF. I didn't bring a change of clothes! 2 days later, we went to CRT, and same thing, only this time I was prepared with the extra clothes!
