To the OP your DD is just lovely, princess or not. I think it is great that she has a wonderful selection of costumes to dress up in and enjoy. One of the most beautiful things to see come alive is a child's imagination. Dressing up can play a huge role in letting all that creativity run free!
My DD, 5, did BBB with her cousins in January and it was a wonderful time for all of us. They each chose a different style so they did not look exactly like the next kid. But even if they did pick the same, who cares? They picked it and they enjoyed it. We went with costumes from home, but if I could have afforded DD would have had more than one and it woudl have been direct from Disney. She really wanted to chose a dress there, but it made better sense for us to bring it and use the money on some other wonderful souvie!!
I would post a picture of the make up pallet they give the princesses at BBB, but I can't right now. To say that the make up was applied with a trowel is just laughable! The children get to keep the left overs and beleive me there is not enough there to apply it heavily let alone with a trowel.. Maybe some parents embellished the make up afterward, but there is not enough to go crazy with in the first place.
The thing to remember is that the BBB is all about your princess getting to live out a fantasy for one day. Let them and you also get to enjoy your child's happiness. Pure, innocent fun. That is all it is.
