Where Tom Hiddleston and David Gandy lead, the rest of us follow.  True blue shirts are making waves on the fashion scene. Adapt your look to modern day but choose a skinnier fit shirt or team your blue shirt with a contrasting yet complementing blue tie. Team with chinos for a typical American boy look or your denims if you’re really channelling the blue vibe. Add trainers for a relaxed look or loafers for business affairs.
