Can I wear a short-sleeved dress shirt?

No. In professional Asia-Pacific business settings, short-sleeved dress shirts are generally viewed as unprofessional or 'office casual' for junior staff. Stick to long sleeves with a suit jacket.

How do I handle the heat when traveling between meetings?

It is standard practice to carry your jacket over your arm while walking between buildings and put it back on before entering the lobby or office. Nobody will think less of you for managing the humidity this way.

Dressing for Business Meetings in Asia-Pacific

Prioritize conservative, high-quality business formal attire, regardless of the heat. Dark suits, long-sleeved shirts, and muted colors are the standard for professional settings across major APAC hubs.

Establish the baseline. In cities like Tokyo, Seoul, and Singapore, 'Business Formal' is the expectation. For men, this means a dark charcoal or navy suit, white or light blue long-sleeved dress shirt, and a conservative silk tie. For women, a suit with trousers or a knee-length skirt paired with a professional blouse is standard.
Account for regional nuances. In Hong Kong and Singapore, dress is slightly more British-influenced, focusing on sharp tailoring. In Southeast Asia (e.g., Jakarta or Kuala Lumpur), 'Batik' shirts are often acceptable for men in business settings, but clarify if you are unsure. Always err on the side of being slightly overdressed.
Master the layers. Air conditioning in Asian skyscrapers is kept at arctic levels. Bring a light blazer or high-quality wool sweater even if it is 95°F (35°C) outside. You will need it inside the boardroom.
Mind the footwear. You will frequently take your shoes off when entering traditional meeting rooms, high-end restaurants, or someone's home. Ensure your socks are clean, hole-free, and dark in color. Leather shoes should be polished and easy to slip on and off.
