I have an open back prom dress. How should I wear my hair?

[serial-thriller]

I wore my hair up in an updo last year for prom and I wore my hair straight and down this year for homecoming. I am at a loss for what to do. It's my last formal dance and I want it to be perfect. I have a little longer than shoulder length hair and side bangs.

 

[seriously]

with any open-back dress you want your hair up to show off the back.
