One Country Where Nobody Wants to Stand Out and One Where Everybody Is Melting: A Fashion Survival Guide

🇰🇷 South Korea · 🇻🇳 Vietnam

By Priya Mehta, The Global Office

In Seoul, some job listings still ask applicants to attach a photo and list their height and weight, and looking put-together every single day isn't vanity — it's treated by locals themselves as adjacent to job performance. In Ho Chi Minh City, the year-round heat and humidity have quietly defeated the tie, the blazer, and most other imports of Western business formality, replacing them with breathable fabrics and a level of comfort that would read as underdressed almost anywhere in Northeast Asia.

Do's & Don'ts

🇰🇷 South Korea

🇻🇳 Vietnam

South Korea's dress culture operates as a genuinely load-bearing part of the social contract, not a superficial add-on to it. Multiple accounts from Korean residents describe appearance pressure as intense and normalized — one Seoul-based professional told researchers the pressure to look good is "beyond imagination" — and the practice extends into hiring itself, with job listings in retail and hospitality sectors sometimes explicitly stating that looks will be a factor, and some companies requesting photos and physical details on applications. Fashion in South Korea, per multiple cultural surveys, favors cohesion and subtlety over individual expression, shaped by concepts like nunchi (social awareness) and jeong (communal harmony) — the goal in daily dress is less "look unique" and more "look correct within your group," a distinction that matters enormously for anyone arriving with a Western instinct to stand out. Professional dress remains formally coded, with coordinated suits still standard in most white-collar office settings even as youth street style trends rapidly through K-pop and social media influence.

Vietnam's dress culture is shaped first by climate and only second by hierarchy, which inverts much of the logic operating in Seoul. Business etiquette guides note the country isn't monolithic: Hanoi maintains a more formal, white-collar dress expectation while Ho Chi Minh City has trended firmly toward business casual, driven partly by climate and partly by a fast-growing tech and creative sector. A 2026 shift documented by Vietnamese business press has seen top-tier firms and agencies in HCMC's District 7 formally abolish traditional dress codes in favor of what's being marketed as "Personal Performance" standards — essentially activewear-adjacent fabrics designed to move seamlessly from a morning workout to a client meeting. Underneath the modern shift, older Confucian-influenced norms persist: modesty is still valued as a form of respect, locals dress neatly even in extreme heat, and the Ao Dai retains real cultural weight, with some female teachers and office workers choosing to wear it on designated days as a point of professional pride rather than nostalgia.

The Reckoning: Both countries treat dress as communicating something beyond personal taste, but they've built that communication around opposite values. Korean dress culture signals conformity and competence through consistency and polish — the message is "I take this seriously and I fit in." Vietnamese dress culture, especially in its faster-moving southern hub, increasingly signals adaptability and comfort — the message is closer to "I'm practical and I keep up." A perfectly polished Korean-style outfit in humid Ho Chi Minh City will wilt by 10 a.m. and may read as slightly try-hard; a relaxed, breathable Vietnamese-style outfit in a formal Seoul office may read as underprepared before a word is spoken.

The Part the Brochure Left Out

Quora — A French expat working in Seoul described being repeatedly asked by well-meaning colleagues why she didn't wear more makeup to the office, and said she eventually adopted a modest daily routine not out of personal preference but because the social friction of not doing so had become exhausting.

Internations Seoul — A Canadian professional noted that the safest strategy she found as a foreigner was deliberate restraint — dressing neatly and quietly rather than trying to match the most fashion-forward local colleague, which she said avoided both looking sloppy and looking like she was performing a culture she didn't fully understand.

Talesmag (foreign service community) — A diplomat's spouse posted in a real-post report on Ho Chi Minh City that ties were essentially decorative there, worn rarely even in client-facing roles, and advised newcomers not to overpack formal business attire they'd end up never wearing in the heat.

Tripadvisor Ho Chi Minh City forum — A long-term expat answering newcomer questions about office dress code repeatedly emphasized bringing a light cardigan for indoor spaces, noting that aggressive air conditioning in HCMC offices and malls was a far more common wardrobe problem than the outdoor heat itself.

Quora — Someone who lived in both Seoul and Ho Chi Minh City for work stints said the biggest mental shift wasn't the clothes themselves but the underlying anxiety level around dress — describing Seoul as "death by a thousand small judgments" and Ho Chi Minh City as "nobody's really looking, just don't overdress."

Conclusion

If you're heading to Seoul, treat your wardrobe and grooming as part of your professional preparation, not an afterthought — the social cost of underdressing is real and persistent. If you're heading to Ho Chi Minh City, pack for the climate over the industry norm you're used to, and don't be surprised when formality quietly evaporates within your first month. Both countries are telling you something true about what they value through what they wear; the mistake is assuming either one is "more casual" than the other rather than casual and formal about entirely different things. My honest advice: in Seoul, over-prepare your closet; in Ho Chi Minh City, under-pack it — you'll buy what you actually need once you're there anyway.
