The 16-to-24 Degree Problem: Five Office Outfits for a Heating System With No Middle Ground

By 9.15 on Monday my desk is 24°C. By 11.40 the window is open and a colleague in a padded gilet is asking whether we can turn the heating up. By 3pm I am carrying a knit vest to the kitchen and pretending it is a design choice. This is not a complaint. It is a brief.

The British office in November is not one temperature. It is a series of microclimates: the radiator by the printer, the draughty corridor by the fire door, the meeting room that somehow holds the heat of a thousand laptops, the lift that smells faintly of wet wool. Dressing for it is less about finding the perfect jumper and more about building a wardrobe that can be edited in a lift, a loo cubicle or the two minutes between meetings.

The rule I keep coming back to

Three layers, one of which can disappear into a tote. A base that can be seen on its own without anyone asking if you are on your way to the gym. Nothing that traps heat at the small of your back. And shoes that can handle a damp pavement without turning your feet into a science experiment by lunchtime.

That is the whole theory. Here is how it looks across a week.

Monday: the merino base and the knit vest

The base is a Uniqlo Extra Fine Merino Crew Neck Jumper, £29.90. It is thin enough to sit under a blazer, warm enough for the 7.48 train and, crucially, it does not make me feel like I am wearing a hot water bottle by 10am. Over it goes an M&S Collection Knitted Vest, £25. Sleeveless means no bulk at the armpits and no awkward sleeve-pushing when the radiator clicks on.

On the bottom half, a pair of Arket Cropped Wool-Blend Trousers, £89, or any wide-leg tailored pair you already own. Shoes are M&S Leather Loafers, £45, with a thin sock rather than a trainer sock because ankles get cold in a draught. The vest comes off at 11am and goes in the tote. It goes back on at 3pm when the sun moves round and the window starts doing its thing.

Styling note: keep the base close to your skin but not tight. The moment a merino jumper is too fitted, it stops being breathable and starts being a sauna.

Tuesday: the shirt that breathes and the cardigan that does not cling

A Uniqlo Rayon Long-Sleeve Blouse, £24.90, is the quiet hero here. Rayon rather than cotton poplin because it does not crease at the elbows after a morning at a keyboard and it does not show sweat patches quite so eagerly. Over it, an Arket Fine-Knit Cardigan, £69, worn buttoned at the top only. That way it looks intentional rather than like you are overheating and panicking.

Trousers are & Other Stories Tailored Trousers, £85, in a mid-grey that hides a multitude of commuter sins. Shoes are Dune London Leather Loafers, £85. The cardigan comes off the moment the radiator clicks on and goes back on for the 4pm slump. The shirt stays put. The shirt is the adult in the room.

Styling note: if you run hot, swap the cardigan for a thin cotton knit. If you run cold, add a Uniqlo Heattech camisole underneath. Nobody will know.

Wednesday: the jersey dress and the blazer that folds

An H&M Ribbed Jersey Midi Dress, £34.99, is the office equivalent of a thermostat you can control. It moves with you, it does not crease, and it looks like you made an effort even when you did not. Over it, an M&S Collection Single-Breasted Blazer, £59, in a stretch fabric that can be folded into a bag if the meeting room turns tropical.

Boots are Clarks Orianna Ankle Boots, £89. Low enough to walk to the station, smart enough for a client meeting. The blazer comes off for the 2pm stretch. The dress stays. The dress is the reason this outfit works.

Styling note: add a thin roll-neck underneath if the office is genuinely arctic. It looks deliberate. It also means you can remove the blazer without feeling underdressed.

Thursday: the knit polo and the slip skirt

A John Lewis Anyday Merino Polo, £45, is a good middle layer because it has a collar and therefore looks like you mean business. Underneath, a Uniqlo Heattech camisole, £9.90, if the commute is cold. Over the top, nothing until you get to your desk. Then a M&S Satin Slip Skirt, £35, in black or chocolate brown. The skirt is cool, the polo is warm, and the boots — Dune London Stretch Knee-High Boots, £99 — are the bit that keeps your legs from staging a revolt.

Styling note: the polo can be pushed up at the sleeves and the skirt can be worn with opaque tights if the office is genuinely cold. Keep a pair of 40-denier tights in your drawer. They take up no space and they have saved me more than once.

Friday: denim, a waistcoat and a very light overshirt

Friday is when the office is emptiest and the heating is least predictable. Levi’s 501 Original Jeans, £90, are the base. A Zara Knit Waistcoat, £35.99, adds a bit of interest without adding bulk. A Uniqlo Flannel Overshirt, £39.90, is the layer that comes off the moment you sit down and goes back on for the walk to the station.

Shoes are Adidas Samba OG, £90, or any clean trainer that can handle a wet pavement. This is the outfit I wear when I cannot be bothered to think and I know I will be at my desk for most of the day.

Styling note: keep the jeans dark and the waistcoat fitted. A loose waistcoat over a loose jean is a lot of volume for a small office kitchen.

The desk-drawer kit

A foldable tote for the layer you shed. A spare pair of socks. Deodorant wipes. A lint roller. A mini hair clip. Not glamorous. Neither is a 24°C radiator in November.

What I would not wear

A chunky cable knit, because it is too warm by 10am and too bulky to take off without looking like you are moving house. A heavy wool coat at your desk, because you will overheat and then go outside and freeze. Dark grey that shows sweat. And tights you cannot remove in a cubicle without a full costume change.

The thermostat wardrobe is not about being clever. It is about being prepared. Five outfits, three layers each, one removable piece. That is the whole trick. The rest is just remembering to put the vest back on before the 4pm meeting.
