I need an easy updo. My hair is normally on the curly side. I need a do that'll stay put the whole night! I am going to a graduation dance. My hair falls past my shoulders when curly (not straightened, just reg.). I need someting very easy and simple, but looks GREAT! I can straighten my hair, curl my hair, but that's as far as I'm going with styling tools. I am wearing a halter dress
