Como: Grey 3-piece suit at Suit Archive Singapore

Quick answer

Business casual is a professional office look: shirt, chinos or trousers, optionally a blazer. Smart casual is a little more relaxed and stylish, allowing darker denim and knitwear. Both usually skip the full suit; a blazer is the easiest way to dress up either.

Key takeaways

  • ✓Business casual is office-focused.
  • ✓Smart casual is more relaxed.
  • ✓A blazer elevates both.
  • ✓Neither requires a tie.
