White and khaki is close to the default office uniform for a reason — the contrast is gentle, the palette is forgiving, and neither piece asks for attention it hasn't earned. The shorter length sits higher at the hip, which reads more current without changing anything about how the shirt actually wears. This is for the office day that starts with a client call and ends with an actual lunch away from your desk. A classic white shirt business casual outfit, updated by a few inches of hem.
Finish with brown leather loafers, no socks if the office allows it.
