Tailored trousers or chinos, a shirt or fine knit, leather shoes. That is well dressed in almost any office.

Office: above 25 degrees?

Linen or a linen blend, a short sleeve with a collar, loafers without socks. Still smart, only lighter.

Air conditioning is colder than outside. Keep a fine knit or a jacket at your desk so your morning does not have to account for it.

Occasion

What to wear to the office

A small set of pieces that works every morning, including the mornings it hits thirty degrees.

Office clothing is not a style problem, it is a logistics problem: you have to get dressed five days a week without thinking. That only works if the pieces you own all combine, and that only works with a small colour palette.

Two neutrals as the base, one lighter neutral for tops, and at most one accent colour. Then every top goes with every bottom and the morning decision disappears.

In hot weather the temptation is to give up on all of it. You do not have to: the answer is fabric, not fewer clothes. Linen, linen blends and fine cotton keep their shape where polyester does not.

The rules, short

The base: Tailored trousers or chinos, a shirt or fine knit, leather shoes. That is well dressed in almost any office.
Above 25 degrees: Linen or a linen blend, a short sleeve with a collar, loafers without socks. Still smart, only lighter.
The layer: Air conditioning is colder than outside. Keep a fine knit or a jacket at your desk so your morning does not have to account for it.
Shoes: Two pairs you alternate last longer than one pair worn daily. Leather needs a day to dry out.
