Dress to Impress, or Dress Like Nobody's Watching: South Korea and the UK Pick Their Poison

🇰🇷 South Korea · 🇬🇧 UK

By Priya Mehta, The Global Office

The British office has, in a decade, loosened its collar considerably. Pinstripes have given way to chinos, Oxford shirts to polo shirts, and the phrase "dress for your day" has entered HR documentation with the gravity of a legal right. Meanwhile, in a Seoul chaebol headquarters, a junior analyst arriving in anything short of a full suit risks the kind of sideways look that says, wordlessly but clearly, that this is not a company that wears its Friday casualness on a Tuesday. Both countries are moving in the same general direction. They are simply starting from different latitudes.

Do's & Don'ts

South Korea

South Korean corporate dress culture is not merely about appearance — it is a visible encoding of hierarchy, seriousness, and institutional belonging. In the traditional chaebol (conglomerate) environment, men in dark suits with white shirts and conservative ties are not dressed for the occasion; they are dressed for the organization, as a continuous declaration of membership. Women are expected to dress in equally formal business attire — suits, tailored dresses, or skirt suits — with visible jewelry considered acceptable if not excessive. The guiding principle is 단정해 보이는 룩: looking neat and composed. Being seen as careless in appearance is, in the corporate culture of large Korean firms, a proxy for being careless in work.

South Korea scores 60 on Hofstede's Power Distance Index and 85 on Uncertainty Avoidance, a combination that produces workplaces where visible hierarchy matters enormously and deviation from established norms carries real risk. What you wear to work is not a personal expression; it is a social signal, and the cost of sending the wrong one is borne by the individual. This produces a conspicuous conformity in Korean offices that can unsettle newcomers: the variation in attire between one person and the next is narrow, deliberate, and by design.

There is a meaningful sector divide, however. South Korea's technology and startup sector has been openly casual for years. Employees at companies like Kakao or Krafton in T-shirts and jeans are standard, and the IT sector has effectively decoupled from the sartorial norms of finance and large corporate groups. The government has even, under various administrations, promoted relaxed summer dress codes to reduce energy consumption (fewer air-conditioned offices trying to offset heat-generating suits). Among workers in their twenties, the appetite for formal dress is declining — one thread on a Korean workplace forum noted the paradox of young employees at traditional companies wearing full suits while their peers at tech firms across the street wore hoodies, and the former being paid less and working longer hours for the privilege.

UK

The United Kingdom arrived at its post-pandemic dress code as a country that had always maintained some ambivalence about formality. The British professional wardrobe has historically been coded not by strict rules but by a set of class-inflected signals: the well-cut suit that signals establishment rather than effort, the deliberate under-dressing of the genuinely secure, the studied informality of the creative industries. What the pandemic did was accelerate a casualisation that was already underway.

By 2025, according to Indeed Hiring Lab UK, 3.3% of UK job postings explicitly referenced casual attire — a figure that peaked at 4.0% in early 2023 as companies competing for talent used dress policy as a recruitment signal. An HRreview survey found 32% of UK employers have adopted "casual — wear what you like, nothing inappropriate" policies, with only 16% maintaining "business smart" standards. Engineering (96.4% of casual-dress references), IT (92.3%), and teaching lead the relaxed sectors. Finance and law lag, maintaining expectations closer to the old conventions, though even in the City of London, tieless suits have become unremarkable.

The generational split is striking. Sixty percent of respondents who opposed workplace dress codes in surveys were under 35; just 5% of the 18–24 cohort supported formal dress requirements. Britain scores only 35 on both Power Distance and Uncertainty Avoidance — among the world's lowest — meaning the cultural machinery for enforcing appearance norms is weak, and the social cost of breaking them, in most sectors, is modest. An expat on r/AskEurope who had moved from Seoul to London described the culture shock of arriving in jeans to a job interview for a mid-size London firm and being told she had dressed entirely appropriately, something that would have been professionally catastrophic at her previous employer.

The Reckoning

Where South Korea uses dress as a visible expression of organizational cohesion, the UK has largely abandoned it as a concept outside specific sectors. Both approaches have internal logic. The Korean system produces visible team solidarity and communicates professionalism to clients in ways that translate across the Korean cultural context; it also burdens workers with clothing costs, restricts personal expression, and creates a visible marker of hierarchy that some employees find alienating. The British system produces freedom and reduces morning friction while creating occasional ambiguity — particularly for workers entering from other cultural contexts who are uncertain whether "smart casual" means chinos or means genuinely casual and whether getting it wrong will be noticed.

The tech sector in both countries has largely converged: in Seoul's startup scene and London's tech cluster alike, the operating assumption is that what matters is what you produce, and clothing is irrelevant. The distinction remains sharpest in finance, law, and large traditional corporate environments, where both countries have their own version of formality — one codified and expected, the other implicit and prestigious.

The Part the Brochure Left Out

Pink Pangea — An American English teacher in South Korea: "I wore a tank top with a cardigan over it and still got in trouble. The cardigan was the saving grace but the neckline was too low by Korean standards. In America it would have been fine. Here, it prompted a quiet word from my supervisor that I still think about."

Quora (What is it like to work in South Korea?) — A former corporate employee at a Seoul conglomerate: "The suit is not optional in a chaebol. I saw a foreign consultant arrive in smart trousers and a blazer — no tie — and the room visibly registered it. Nobody said anything. Nobody had to. The consultant wore a tie the next day."

r/korea — A commenter on an office attire thread: "My colleagues at the startup two floors up are in hoodies and headphones. I am in a suit. We are in the same building, earning different salaries, working different hours. I am not sure the suit is doing what management thinks it is doing."

r/AskEurope — An expat who relocated from Seoul to London: "I asked HR what the dress code was. They said 'smart casual.' I asked what that meant. They said 'you'll figure it out.' I wore a blazer and dark jeans on day one. I was overdressed by about one layer. Nobody said anything. In Seoul, nobody would have needed to."

Internations (South Korea expat community) — A Western expat working at a mid-size Korean firm: "The unwritten rule is: dress at the level of the most senior person in the room, or one notch below. Dress above them and it's presumptuous. Dress far below and it's disrespectful. The window is narrower than you expect, and there is no document explaining it."

Conclusion

South Korea treats formal dress as a collective commitment — what you wear is a statement about your relationship to the organization, not to yourself. The UK has moved toward treating it as an individual choice — what you wear is your own business, as long as it clears an unremarkable threshold. The honest outcome of British dress freedom is that clothing has become a class signal, which is perhaps what it always was, just less explicitly. The honest outcome of Korean dress formality is that clothing has become a compliance cost, which is perhaps also what it always was.

In neither country has the question of whether any of this matters been resolved, merely deferred — usually until the next hire arrives in the wrong outfit and everyone pretends not to notice.
