Business casual for men.

A simple crewneck can be a useful base in a relaxed office. Check whether your workplace expects a collar instead. Try the hem loose and lightly tucked; the shoulder, sleeve and waistband should allow movement without pulling.

Choose trousers for your preferred silhouette, whether straight, tapered or wide. Excess cloth pooling on the shoe can make a useful pair feel unfinished; an appropriate hem often makes more difference than another purchase.

Roomy does not have to mean oversized everywhere.

The white waffle crew and grey trousers appear beneath both the cardigan and checked blazer. Compare the outer lines: the cardigan adds texture, while an open blazer gives the shoulder more structure. Keep room through the upper arm so neither layer strains.

For a more formal client meeting, a structured jacket and dress shoes may be useful. If the invitation asks for business professional or a suit, move to that level instead of assuming a blazer makes every casual base sufficient.

Let the meeting decide how much structure to add.

Loafers, derbies and other polished shoes are dependable starting points. If your workplace allows sneakers, choose a clean pair that suits the rest of the outfit, rather than treating running shoes as a default.

Wear the socks and footwear you intend to use when checking the trouser length. For a long commute, comfort and weather matter; specialist work and safety requirements always take priority.

Repeat a good shoe rather than buying a different pair for every outfit.
