The Season

What actually changes through the year — and the part of the seasonal advice that is being sold to you.

Where we are now

The shoulder season is the hard one

Late August is the most awkward stretch of the year to dress for, and it is the least written-about. Summer clothes still work at two in the afternoon and are wrong by eight. The instinct is to reach for autumn early, which reads as costume in eighty-degree heat.

The useful framing is that the shoulder season is not a season with its own wardrobe. It is summer's structure in heavier cloth.

There is a category of cloth that exists for exactly this and gets almost no attention: wool gabardine, whipcord, worsted tweeds — things that wear warmer than true summer fabrics without trapping heat like real tweed. They sit deliberately in the middle.

“It's a shoulder season cloth, which means it helps you stay cool in the spring and warm in the fall.”

Derek Guy, Die, Workwear! · February 1, 2017

The substitution, stated plainly

Instead of linen sport coats, worsted tweeds. Instead of lightweight chinos, whipcords. Crinkly linen shirts swap for heavier oxfords and brushed tattersalls. Same outfit, heavier cloth — reported from a September in which, as the writer notes, the cold season keeps getting pushed back.

The mechanism

Weave beats weight, and both beat color

Most seasonal advice sorts fabrics by how heavy they are. That is the second most important variable, not the first. How open the weave is decides how a cloth wears, and it can reverse the weight ranking entirely.

The test takes five seconds and works in a shop: hold the cloth up and see how much light comes through it.

Two consequences that sound wrong and are not. Linen is often cooler in a heavier weight, because it flows rather than clinging. And linen's real advantage over cotton is that it moves moisture, not that it is more porous — it can be woven as tightly as any other cloth.

“An airy 10oz tropical wool will wear a lot cooler than a densely woven, 14oz Irish linen.”

A disagreement we are not going to resolve for you

The claim that light colors keep you cooler rests, in everything we could verify, on a single commercial source — and the higher-authority ones contradict it. One ranks color well behind weave; another argues for darker colors in sheer summer shirting, to stop it going transparent. Treat it as contested.

Palettes

The four sets, as published

These are quoted rather than invented, and they are more specific than the usual advice to wear 'earth tones in fall'. Each is a real list from a dated source.

Spring

Gabardine · mock leno · hopsack 12–14oz

Oatmeal, pale greens from olive through sage, tobacco brown, dark brown, sandy beige, dark green, rust check, navy. The least documented season of the four — worth knowing that the guidance here is thinner than it looks everywhere else.

Die, Workwear!, March 14, 2020 · Put This On, April 22, 2022

Summer

High-twist 9–13oz · linen 7–13oz · hopsack 8–10oz

Tan, cream, olive, tobacco brown, cigar brown, and Royal Air Force blue. Irish linen runs 10–13oz; Italian linen is lighter and quoted in grams, 200–280g. A summer blazer wants the darkest navy there is.

Put This On, June 12, 2017 · Permanent Style, May 28, 2018 and July 7, 2023

Autumn

Corduroy 270–350g · flannel 13–15oz · tweed 17–18oz

Bark, moss and heather. Dark brown and dark green are the best starting points for corduroy; tan, wheat and cream for trousers. Flannel wants gray in a mix of shades, and navy. Muted only — this is not the season for a strong color.

Winter

Overcoating 600–700g · brushed shirting 180–200g

Burnt greens, creams, mid-to-light gray, every shade of brown and beige. Knitwear in priority order: gray, then navy, then brown, beige and cream, then green, then charcoal and black, and strong colors last. First overcoat navy, second charcoal.

The correction

Rotate straps for the material, not the calendar

We had this filed as settled and it was half wrong, so we are correcting it in public rather than quietly.

The suspicion was reasonable. Nearly every article recommending a seasonal strap rotation is published by somebody who sells straps — in two cases we checked, the author is the outlet's own retail editor or the designer of the straps being recommended. That is as clear a conflict as this subject offers.

But the argument turns out not to depend on those sources. An outlet that sells no straps at all makes the same case on physical grounds: sweat is salty and mildly acidic, a watch strap sits against skin more constantly than any other leather good you own, and wrists genuinely change size in heat, which is a sizing problem for a fitted bracelet rather than a matter of taste.

The tell that persuaded us: the single most conflicted source in the set uses the argument to recommend a cheap fabric liner so that one strap lasts longer. Someone arguing against their own sales is probably telling you what they actually believe.

Where the line falls

Rotating to protect leather from sweat, and for a fit that changes with temperature — supported, and physically sensible. Rotating because a watch is a 'summer watch' — that is a retail genre. One respected editor who sells nothing changes straps by outfit rather than by season, which we think is the better instinct.

Summer, specifically

What survives the water

The best evidence here comes from a writer who tested it properly — he swam in the ocean in each option rather than reasoning about them. His ranking: quality rubber and a steel bracelet tie for first, sailcloth third, and fabric NATO last. A second writer with nothing to sell arrives at nearly the same order independently.

That result surprises people, because NATO has a summer reputation. The problem is that nylon stays wet long after you are out of the water and goes slippery while it is. Its real virtue is security — it threads behind both spring bars, so a failed spring bar does not lose you the watch.

Two practical notes. Choose genuine rubber over silicone, which discolors quickly. And a steel bracelet in direct sun gets hot enough that both writers raise it unprompted — one goes as far as saying he can imagine somebody being burned by it.

Three things we could not source, and are not going to assert

Sunscreen and chlorine damage, gasket degradation, and the popular 'size your bracelet in the afternoon' rule. The underlying premise of the last one is verified — wrists do swell in heat — but the rule itself appears only in retailer blogs. A line attributing sunscreen warnings to a well-known summer strap guide turns out not to be in that article at all.

Winter, specifically

Over the cuff is a costume, and it has a named origin

Wearing a watch on top of the shirt cuff has one famous source — Gianni Agnelli — and essentially every menswear authority treats copying it as a mistake, for a better reason than 'it looks odd'.

The watch press is neutral on this and describes it as uncommon but done. The tailoring press is not neutral. The strongest objection is not about the look at all: an idiosyncrasy that belongs to one person stops being an idiosyncrasy the moment it is a technique.

The other winter constraint is knitwear rather than shirting. A tall case with sharp lugs catches on a fine knit, and pushing knit sleeves up to clear a watch will stretch them permanently — which is covered properly in The Fit.

“I wouldn't copy something so distinctive to one person. Those sprezzatura looks are meant to be highly individual. Copying someone else's kind of ruins the point.”

Simon Crompton, Permanent Style · September 14, 2020

Not verified — so not claimed

Titanium feeling warmer than steel in cold weather is real physics, but we could find it asserted only by metals suppliers, never in dated watch writing. The same goes for leather stiffening, rubber hardening and cold affecting lubricants. Our Ager is titanium; we are still not going to tell you it feels warmer, because we cannot show you who established that.

The rules that are not rules

No white after Labor Day, and other fossils

No authority we could find defends it. The tracing runs to 19th-century class signaling rather than to anything about cloth or weather. The seersucker windows people quote — Easter to October, or Memorial Day to Labor Day — are deflated even by the traditionalist sources that repeat them, as rough markers for the hottest part of the year rather than dates.

There is also a respectable dissent from the whole idea, worth hearing because it comes from inside the most seasonally-minded publication there is.

Our position is somewhere between. Rotating a wardrobe by season is not etiquette, it is a way of keeping things enjoyable — and that is a much better argument for it than propriety ever was.

“I'm not a huge believer in only wearing certain cloths at certain times of the year from a propriety point of view. Usually it's just a case of wearing more or fewer layers.”

Jamie Ferguson, Permanent Style · March 19, 2025

The idea worth keeping

Summer is a white canvas

The best line we found all year, and the one that makes the case for seasonal dressing better than any rule could.

The same writer keeps four wardrobes and rotates them, and gives the honest reason: things you see every day stop registering. If everything is available all year, nothing feels like an occasion — including the watch you chose that morning.

“Dressing in autumn is a little like painting. If summer is a white canvas, as it turns into winter color and texture are added until the picture feels complete.”
