I tried a couple khakis, one the classic beige, and another was dark brown. They both looked a bit tacky and didn't quite work (style aside, the color didn't seem quite right). What color and style of pants would go good with that coat and shirt?
The purpose is for job interviews. I'm gonna wear a artistic, classy looking piano necktie, since I'm a pianist. Not some cheesy playable piano key necktie, but an artistic one. It should make me stand out some.
It would be helpful if you'd included all the pieces of your proposed outfit. I personally don't like the idea of wearing pants a different color than the jacket. Black and white does not go with brown pants of any shade no matter how artistic.
Unless you're interviewing for a pianist position, do not wear the piano tie.
