A tie and a pocket square are chosen for one small agreement, a colour, a pattern, a weight, and left to differ on everything else. That single point of contact is what gives a pairing its quiet authority.

Take a check tie and a square in a single shade drawn from it. The rest is left to its own instincts. It is a small act of restraint, and it is the whole art of the thing.

The pairing should feel deliberate. Never obvious.
