**The office blazer outfit starts with one blazer: single-breasted, in a mid-weight wool blend, with shoulders that end at the shoulder and sleeves that show a half-inch of shirt cuff. Wear it three ways: over a shirt with trousers for a formal day, over a tee with wide-leg trousers for a smart day, and open over a dress for a meeting. The blazer works because it frames the outfit, and the fit is what makes it look expensive.**

## The fit is the whole purchase

The blazer is bought on fit, not on brand, and the fit is checked in three places. The shoulders should end at the shoulder, not droop past it and not pull in short of it, because the shoulder line is what makes the blazer look tailored. The button should close without pulling, and the sleeves should show a half-inch of shirt cuff, which is the detail that makes the whole outfit look deliberate. The length should cover the hip without reaching the thigh.

Try the blazer on with the clothes you will actually wear under it, not with a tank top, because a blazer that fits over a tee and pulls over a shirt is the wrong size. Sleeve shortening is cheap tailoring and worth it on an otherwise good blazer, while shoulder alteration is expensive and usually not worth it, so buy for the shoulders and tailor the sleeves. A blazer that fits in the shoulders and the button is a blazer that looks expensive at any price.

## Three ways to wear the one blazer

The one blazer earns its place by working three ways. Over a shirt with tailored trousers, it is the formal day outfit, the one for client meetings and presentations. Over a simple tee with wide-leg trousers, it is the smart day outfit, polished without being formal. Open over a dress, it is the meeting outfit, adding structure to a piece that would otherwise read as casual. The blazer does not change; the layers under it do.

The colors that work are navy, charcoal, and camel, with black reserved for a blazer paired with a different color trouser, not a matching black trouser in the same fabric, which reads as a suit that lost its jacket. The rule is that the blazer is the frame and the layers under it carry the color. One blazer, three outfits, and the fit doing the work in all three is the formula.

## The details that make it look expensive

The details that separate a good blazer from a cheap one are small and visible. A lined blazer hangs better and lasts longer than an unlined one, and the lining should be smooth, not bunched at the back. Horn buttons look better than plastic ones and age better, and the lapel width should suit the wearer's frame, narrower for a smaller frame and wider for a broader one. A pocket square is optional and should be plain, not patterned, if the shirt is patterned.

The maintenance is simple: steam it rather than ironing it, because ironing flattens the lapel and the shoulder. Hang it on a wide wooden hanger, not a wire one, so the shoulders keep their shape. And the cost-per-wear math is the real test: a $240 blazer worn 60 times costs $4 a wear, while a $70 blazer that pills and gets retired after 6 wears costs nearly $12 a wear. The expensive mistake in most closets is the cheap blazer.
