What is a foolproof business casual outfit formula?
Knit or button-down + tailored trouser + leather shoe + one structured layer. Four slots, endless variation.
Business casual fails when it drifts toward either endpoint - too formal (full suit energy) or too casual (weekend energy). The safe template: a fine knit or pressed button-down on top, a tailored trouser (not a jean, not a chino you mow lawns in) below, a leather shoe that is not a sneaker, and a blazer or structured cardigan when the room runs cold or formal. Everything interchangeable within your palette means you can assemble it in the dark. Keep one complete version of this outfit clean and ready at all times for surprise meetings.
