Hair styles to mach my dress?

Next week, I am graduating! (from middle school lol). Anyways, my dress is an Ivory color, with a black sash. It is a little above my nee and is strapless. What hairstyles are good for strapless dresses? I am going to get my hair done at a salon, but I need a style to tell them. My hair is a chocolate brown color, and it is long and wavy. I have long bangs that are tinted red, so I can do anything. I am really tall so it makes the dress look shorter. Oh, and my face is heart/round-ish shape, please help?
