I need help with my hair!! Trying to impress a guy kinda :)?

So I like this guy and I don't want to look like a slob, but I want to look casual. I am wearing a tie-die V-neck T-shirt tomorrow skinny jeans with converse???? How should I wear my hair? side braid? Curly? Straight? Up??? Any other ways? Oh! Idk if this helps but I have light brownish hair and light blue eyes. Thanks to all who answers :)
