Half up/half down is a neat but pretty look, and if done correctly it's very sophisticated. Follow Natalie's lead and part your hair far to one side, right above your eyebrow's arch. Then gather and pin the front section of your hair. You can use a barrette, or simple bobby pins. Use a medium-sized curling iron to curl the ends if you'd like, and then create a little more volume by curling the top layer of hair.
