Curl your hair, scrunch it with hairspray or gel, braid it at night so it's crimped in the morning, pigtails, messy bun, twist a little bit of hair above your forehead and straighten curl or put the rest of your hair up, take a paper lunch bag cut it into strips and wrap wet hair into it and sleep with it in do your hair is curly
I would also suggest plaiting your hair, similar to braiding but with 4 strands. Your hair will be out of your face and the checkerboard design will look lovely on the back of your head. Even more interesting if you have different shades of hair color. I did this many years ago and I just loved it. Good luck!
Long hairs do not have a lot of styles that one can choose from. But, it looks smart when it is braided, you many try to braid it and you will at least stay for some days without thinking of a style to comp it.
