I have a job interview next week in the accounting department of the college I just graduated from. I'm wondering what would be the best way to style my hair for a professional, but casual, look. Because it's at a college the offices seem to be a little more on the casual side, but I want to look mature and adult. My hair is still quite similar to my pictures, BSL with shortest layers a little below my shoulders. I'll be wearing a white, long-sleeve button up shirt, dark slacks, and black heels. Would it be more professional to style my hair, i.e. straighten or put some loose waves in it, or to put it up? And if I put it up, what would be an attractive and understated style that would work well with layering (and little hair experience because I'm a hair noob)? I want to make the best impression that I can because it's been a long time since I've had a job interview (or a job. :/).
