I dont normally like these jackets but this one looks good. Every business man needs a definitive sports jacket. Checkered blue jacket with a small yet eye-catching lapel pin (in maroon, no less) works wonder with in an otherwise plain blue/grey ensemble.
A smart casual combination of a black sportcoat and dark blue chinos can maintain its relevance in many different circumstances. Show your sartorial prowess with a pair of navy blue suede tassel loafers.
