Your blue sports jacket doesn't always have to be a solid coloured one. This is a nice alternative in a blue herringbone tweed woven by Lanificio Di Pray in Italy. The cloth is lighter in weight than the classic Scottish tweeds. Just remember that the Ring Jacket's fit is superior compared to most what's out there.
