What does smart casual mean?

Smart casual explained simply, with three ready-to-wear outfits for men and women and a quick list of what counts as too casual or too formal.

By Style the Rest · Updated · 3 outfits

Smart casual sits between a suit and weekend clothes. It means looking polished and put-together without being formal: no tie needed, but no gym wear either.

A simple way to get it right: combine one smart piece (a blazer, a shirt, tailored trousers, leather shoes) with one casual piece (dark jeans, a knit, clean sneakers).

3 ways to wear smart casual

Office parties, dinners, interviews at relaxed companies

The Reliable Blazer

Blazer and shirt on top are smart; dark jeans keep it casual. It's the safest smart-casual formula there is.

Tip Dark jeans with no rips are essential; anything faded tips it into casual.

Work, client lunches, family events

Polished Knit

Tailored trousers and loafers are smart; a soft knit keeps it relaxed. Cream and black look crisp, and tan leather adds warmth.

Tip Tuck the front of the jumper in slightly to define the waist.

Garden parties, summer evenings, holidays

Summer Smart Casual

Linen is breathable and relaxed, but a buttoned shirt with tailored trousers and loafers keeps it smart.

Tip Linen creases; that's part of its charm, but start with it freshly steamed.

The rules

  • One smart piece plus one casual piece is the easiest formula.
  • Swap trainers for loafers, desert boots or clean leather sneakers.
  • Dark, unripped denim counts as smart casual; faded or distressed denim doesn't.
  • When unsure, slightly overdressing is safer than underdressing; a blazer can always come off.

Skip these

  • Gym wear, hoodies or sportswear logos
  • Ripped jeans and flip-flops
  • A full suit and tie (too formal)
