What Is Business Casual Attire?
Business casual is the sweet spot between polished and relaxed. Think smart blouses, midi dresses, tailored trousers, and structured blazers — the kind of outfit that looks professional but not overly stiff.
Unlike full business formal (suits, tights, and neutral tones only), business casual allows a bit more freedom in colour, cut, and coordination. Items like wide-leg trousers, well-fitted blazers, and classic loafers are all part of a modern business casual rotation.
Smart Casual vs Business Casual: What’s the Difference?
The smart casual vs business casual debate comes down to structure vs spontaneity.
Smart casual lets you play — elevated jeans, bright knits, and fashion-forward accessories. It’s ideal for creative offices or hybrid setups. Think loafers, relaxed blazers, or patterned shirts.
Business casual, by contrast, usually leans more classic: shirts and blouses, neutral palettes, and more tailored silhouettes.
The best tip? Observe your team’s style and lean one notch more polished.
How to Dress Business Casual
Getting dressed is easier when you know the rules. Here's how to build a business casual wardrobe:
-
Trousers: Stick to structured, neutral-coloured styles — wide-leg, tapered, or cropped.
-
Blazers: A go-to for instant polish. Opt for classic cuts and wear over dresses, tees, or blouses.
-
Jeans: When appropriate, choose dark-wash, non-distressed styles.
-
Jumpers: Layer light knitwear over collared shirts for a polished vibe.
-
Dresses or Jumpsuits: Stick with midi or tailored styles in solids or subtle prints.
-
Tops: Choose blouses, button-downs, or knits that are modest yet stylish.
-
Skirts: A-line or pleated options work best. Avoid overly short lengths.
-
Co-ords: Matching sets or structured separates make dressing effortless.
-
Shoes: Closed-toe flats or low heels are always a safe bet.
