Navy and khaki is close to a default setting for business casual, and it earns that status honestly — the deep cool blue and the warm tan sit far enough apart to read as a choice, not an accident. The shirt holds its shape through a full day of desk work without needing a re-tuck by 2pm. This is the outfit for back-to-back meetings where you don't want to think about your shirt again until you take it off. It's the kind of business casual outfit for men that a hiring manager, a client, and your own reflection can all agree on.
Finish with brown leather oxfords and a slim brown belt to match.
