Is business casual acceptable?

Generally, no. Even if the office seems relaxed, your first impression should be formal. If you are told specifically that the office is 'business casual,' opt for a blazer and dress trousers rather than chinos and a polo shirt.

Do I need to worry about my socks?

Yes. Since you will likely take your shoes off when entering traditional meeting spaces or restaurants, ensure your socks are clean, hole-free, and dark-colored.

What if I am visiting a tech startup?

Tech companies in Pangyo or Gangnam can be more casual. However, when in doubt, default to formal. It is better to be slightly overdressed than underdressed.

Dressing for Business Meetings in Seoul

Dress conservatively in high-quality, dark-colored professional attire to match the formal corporate culture of South Korea. Aim for a 'business professional' look rather than 'business casual,' prioritizing a polished, clean appearance above all else.

Select your color palette. Stick to dark navy, charcoal, or black suits. Avoid bright colors, flashy patterns, or unconventional cuts, as these can be perceived as unprofessional in traditional Korean offices.
Focus on fit and fabric. Ensure your suit is well-tailored and pressed. Fabric quality matters; natural fibers like wool or high-quality blends are preferred over synthetic, shiny fabrics.
Accessorize minimally. Keep jewelry simple and subtle. For men, ties should be solid colors or conservative patterns. For both, ensure leather shoes are polished and in good condition, as you may be required to remove them when entering certain meeting rooms.
Plan for the season. Seoul has extreme weather. In winter, wear a high-quality wool overcoat. In summer, prioritize breathable lightweight wools for meetings, as the humidity is high but AC in offices is very strong.
