I know that I am opionated and conceited... but I do think a corduroy suit makes a hell of a statement. I also don't think brown/brown is a no-no. But, vary the shades of brown. If the suit is dark brown London Tan shoes and belt would do nicely. Also, as someone else said here, keep the shirt/tie/accessories plain with a cord suit. flaunt your style, after all, no one else will!
