Classic safe pairings: navy suit + white shirt + navy or burgundy tie; charcoal suit + light blue shirt + silver-grey or purple tie. JEREMIAH SUIT advises mastering these foundations first.
Advanced principle: the tie may sit one shade darker or lighter than the suit; the shirt acts as transition layer and should be lighter than both. Avoid high saturation across all three elements.
JEREMIAH SUIT fitting services offer colour consultation adjusted for complexion and hair—the same navy may need different shirt tones on different clients.
