if you're like me, with very strong-willed straight hair, you shouldn't even bother curling it. just put a fancy hair tie in. Or twist it around a little and clip it up with one of those big claw clips.
Curl it...this way it will stay out of your food.
Well I would do what ever you are the most confertable with. Then I would ask who are you trying to impress.
tie up in a ponytail...keeps the food out of it.
Do whatever you want as long it's presentable to your date I'm assume ...
