What dress do you think she should wear?

Next Tuesday is the first day of KINDERGARTEN!! K. is my first child to enter the public school system; and the kindergarteners go all day. As happy as I am for her to go, I'll miss her during the day. (I needn't worry about being bored, I've got Little S. and D. to chase after.)

I'd like to ask your opinion on what dress K. should wear on her first day. I really want her to look cute and nice and I don't care if she wears it on the playground or whatever. You only have ONE first day. (in grownup terms, you get one shot at a first impression.)

Here are the options... so far. All of the dresses are a little big but the ones that fit well are just a tad too casual. She can wear them on the 2nd day and so on.

I've created a poll over on the side so you can vote but by all means, leave me a comment. I have to take K.'s opinions into this too so don't be upset if I don't choose your favorite or even the one that gets the most votes. Since I'm incapable of making a decision on my own, I wanted to see which way I should sway her.
