There is a cardigan on the back of a chair in every office in Klang Valley, and it has never once been worn outdoors. That garment is the single most honest piece of Malaysian fashion criticism ever produced.
Outside it is 32°C and humid enough to fog a camera lens. Inside the meeting room on level 14, it is cold enough that people cup their coffee for warmth. The national wardrobe was not built for the first number. It was built for the second.
The 24°C rule changed the brief
In April 2026, Deputy Prime Minister Fadillah Yusof announced that government buildings would tighten energy controls, including setting air-conditioning at no lower than 24°C. The reasoning was the global energy crisis and the electricity bill, not comfort — but the side effect is a change to how offices actually feel.
The numbers behind it are not trivial. Raising a building from 22°C to 24°C is estimated to cut air-conditioning energy by around 14 per cent, which works out to roughly seven to eight per cent off a building's total electricity consumption. Energy specialists quoted by Bernama framed it as one of the cheaper efficiency levers available, and The Edge reported it as part of a wider tightening of energy use across government buildings.
And notably, the announcement came with a wardrobe note attached: civil servants were urged to wear attire better suited to the local climate — batik, corporate shirts, baju Melayu — rather than dressing for a cooling system.
That is a small sentence with a big implication. For decades the causality ran one way: the office was cold, so we dressed warm. The rule flips it. Dress for the country, and the country spends less on cooling it.
Why the cardigan exists in the first place
The Malaysian office cardigan is not a fashion choice. It is an adaptation.
Somewhere in the 1990s, Malaysian commercial buildings settled on a default that sat well below the recommended indoor comfort band of roughly 23°C to 26°C. Nobody voted on it. Facilities set it, nobody complained loudly enough, and two generations of workers built a wardrobe on top of the decision.
The knock-on effects are everywhere once you notice them. Long sleeves in a tropical country. Blazers in August. Scarves — actual scarves — worn indoors in Bangsar South. Socks kept in a drawer because the tile floor of the pantry is genuinely unpleasant. Meanwhile the commute between the car park and the lift lobby is a 90-second sprint through a wall of heat, in clothes designed for the opposite condition.
The result is a wardrobe that fails at both ends. Too warm outside, not quite warm enough inside, and expensive because you are effectively buying two seasons in a country that has one.
What actually works at 24°C
A slightly warmer room does not demand a new wardrobe. It rewards a slightly better one.
Natural fibres, finally justified. Cotton, linen and linen blends breathe in a way that polyester-heavy corporate shirts do not. At 22°C the difference is invisible. At 24°C and above it is the whole ballgame.
Batik as a genuine office answer. Batik has been the officially encouraged option for years, and it has the advantage of being made for this climate rather than adapted to it. KL offices had already been warming to it — we wrote about batik moving from Thursdays to every day earlier this year.
Modern baju kurung and baju Melayu. A wave of Malaysian labels has been rebuilding traditional silhouettes in lighter, more office-appropriate constructions. Our roundup of the labels turning baju kurung and baju Melayu into office wear covers who is doing it well.
Layers you can remove, not layers you must keep. The cardigan works because it is optional. The blazer that is structurally part of the outfit does not.
Shoes that survive the walk. The 90-second heat sprint is the part of the day most workwear ignores entirely. Closed shoes that breathe make more difference than any shirt.
The two-wardrobe problem is a spending problem
The quiet cost of the cold office is that Malaysians buy clothing for a climate they do not live in.
A blazer bought for air-conditioned meeting rooms is a garment worn perhaps thirty minutes a week, in one building, for one reason. It cannot be worn to lunch. It cannot be worn on the weekend. It is single-purpose spending disguised as a wardrobe staple, and it is dictated entirely by a thermostat setting that most people have never seen, let alone controlled.
A wardrobe built for 24°C rather than 22°C is a smaller wardrobe. Fewer items, more wear per item, and less of that specifically Malaysian experience of owning winter clothing in a country with no winter.
None of which means the cardigan disappears. Cold rooms are not going away everywhere at once, and buildings vary wildly. But the direction has shifted, and for once it points towards dressing like where we actually are — which, for the record, includes the fact that selipar Jepun remains the national footwear the moment the office door closes behind us.
FAQ
What is Malaysia's 24°C air-conditioning rule?
In April 2026, the Deputy Prime Minister announced that air-conditioning in government buildings would be set at no lower than 24°C as part of tightened energy controls in response to the global energy crisis. Civil servants were also encouraged to wear climate-appropriate attire such as batik, corporate shirts or baju Melayu.
How much energy does raising the aircon to 24°C save?
Raising a building from 22°C to 24°C is estimated to reduce air-conditioning energy use by roughly 14 per cent, translating to around seven to eight per cent off overall building electricity consumption.
What temperature is comfortable for an office?
The commonly cited indoor comfort range is approximately 23°C to 26°C. For comparison, Singapore's public sector guidance sits around 25°C, India around 24°C, and Japan around 28°C.
What should I wear to a warmer Malaysian office?
Natural fibres over synthetics, batik or a lighter modern take on baju kurung and baju Melayu, and removable layers rather than structural ones. Breathable closed shoes matter more than most people assume.
