Blue Line picks up a thread that runs back through the label's earlier Travel Collection shirts, still earning the name with a pale blue-and-white pinstripe in pure cotton, cut with a neat band collar and mother-of-pearl buttons up the front. The standout detail is the single chest pocket, cut deliberately against the grain of the body's stripes so the pattern runs crosswise across it, a small piece of pattern-cutting that keeps the shirt from reading as plain. The fit is loose through dropped shoulders, with wide turn-back cuffs finishing the sleeve and a gently curved hem, all of which suits a shirt meant to be lived in rather than pressed. Like its predecessors, the idea here is practicality: packable, unfussy, and forgiving of a day spent in transit, with the pinstripe keeping things graphic without shouting. For off-duty days, try it with the Marseille Pants in Japanese Raw Denim.
