I am in the market for a formal briefcase, maybe from Papworth or Swaine Adeney. I think that tan is the most handsome of the choices, but as I am in a very conservative industry, I assume that I am limited to either Havana or black. While I would prefer Havana to black, I only have and wear black shoes. Would you say that brown briefcase with black shoes combination EVERYDAY is not recommended? Also, your opinions on nickel instead of brass hardware? Thank you!
