I have an interview coming up, and I want to look really professional and polished. I don't really know what to do with my hair. I have dark longish hair (about 1-2 inches above my bra strap) and it's sort of wavy but not really - I straighten it but not pin-straight. My bangs are side-swept but I want them out of the way because I will play with them if I get nervous and I want to look mature. I was thinking of a dark thin hairband or a low ponytail? Please help!
