How should i style my hair for school. Im 13 and want a cute easy unique hairstyle please answer?

if you try this over night, then have a shower, then twist 2 pieces of hair around eachother and sleep with it like that, when you wake up just run your fingers through your hair and its cute and has beach waves :) or you can do a messy bun. if you dont want a plain old messy bun, then when you are pulling your hair back, then twist some of the strands and pull them back. then theres twist around your head followed by the messy bun. easy and cuute! :)
