For long hair, a classic pony with a little texture and volume is always a nice option.

Another bun at the nape of the neck, this time with some bobby pins to hold back those flyaways on the sides. (And don't forget the fun earrings.)

You could always just gather all your hair to the side with a pretty clip for a romantic look.
