White keeps this sharp, and storm green keeps it from reading like just another gray-pant office outfit. The shirt has enough stretch to move through a full day of meetings, and the pants are finished with a tapered leg that still looks clean standing at a whiteboard. Picture the 9am huddle, coffee in hand, no second-guessing what's on below the desk. It's a solid answer to business casual without a blazer, one less decision before the first meeting starts.

Finish with brown leather derbies and a slim brown belt.
