For a trade business headshot, wear what you wear on the job. A clean work shirt with your own logo photographs better than a suit, because it matches the person who will actually knock on the customer’s door.

Solid mid-tone colors work best. Avoid tight stripes and small checks, which can shimmer oddly in photographs, and avoid a large logo or slogan across the chest that competes with your face for attention.

Do not wear something brand new that you have never worn. New clothes sit stiffly and people look uncomfortable in them, and looking uncomfortable is the one thing a trust photograph cannot afford. Bring a second shirt if you are unsure and decide on the day.
