This is a shoppable look: click any numbered marker on the photo, or any card beside it, to jump straight to that piece. It is a starting point for four items that work hard together, not a single outfit you have to copy exactly.

The blazer is the piece that sets the whole outfit in motion. A single-button, notched-lapel cut like this one works over a plain shirt for the office or over a simple tee on the weekend, so it earns its place even if you only wear the rest of the look occasionally.

Underneath, a classic cotton poplin shirt keeps things uncomplicated and lets the blazer and trousers do the talking. Wide-leg trousers add the drape that makes the whole silhouette feel considered instead of thrown together, and a black loafer keeps the proportions grounded.

None of these four pieces are locked to each other. Swap in a shirt or trousers you already own, or use this shortlist as a jumping-off point and substitute your own colors once you have the shapes right.
