Well its gotta be a ponytail.





And I know you don't want to cut it, but you should think about taking the length up a little, to myabe 3 inches past your shoulders. Mid back may be a little too long. Plus your hair would still be long.Formal hair style for a man with long hair?
Slick it back in a pony-tail with hair gel. I know a lot of my friends did that for prom.
