How should I have my hair for tomorrow's job interview?

I've narrowed it down to two options, option one is straightening it and putting my fringe out of my face with a hair slide, and option two is putting it up in a sort of 'messy bun/bow' type thing.. I'll be wearing black trousers, a black blouse with silver buttons and black ballet pumps with tiny silver studs/dots on the tip.
The interview is for New Look and I'm 17. Also, my hair is just below shoulder length.

I would keep it with straight with the slide, a messy bun is more of a fun / look sexy thing. It will not be suitable for an interview . Once you get the job you can do the bun thing.

Based on what your wearing, a messy bun would be appropriate. Good luck!

I think that the first option will make you look professional whilst the second option will make you look charismatic
