What type of hairstyle should I do on the first day of school?

I am moving from my old school after 6 years to a new one, and I don't know what hairstyle to do on the first day of school...I want to do something girly and fun. (because I am girly) I am wearing a yellow dress with a plain white top under neath and white leggings with white and yellow flats. I have long layered DARK brown hair. Help????
