Before the Brief: Loincloths, Fundoshi and Four Thousand Years
Linen in Tutankhamun's tomb, leather trunks in a London well, a length of Japanese cotton: the history of underwear before briefs, over four thousand years.
The Y-Front at Ninety
The Y-front went on sale in a Chicago window in a 1935 blizzard. Ninety years of Coopers, Lyle and Scott, and the fly that turns out to be proper engineering.

The ninetieth birthday of the most consequential men's garment of the twentieth century came and went in January of last year and almost nobody marked it. No exhibition. No anniversary edition. A little press written in the tone people reserve for things their grandfathers owned, and then everyone went back to what they were doing.
In any other category the comparison would be embarrassing. A watch complication in continuous production since 1935 would have its own book. A car engine architecture that old would be the subject of an annual gathering in a field.
The overlapping front opening on a men's brief gets none of that, and the reason is not that it failed. It is that it succeeded so comprehensively, for so long, on so many men, that it became the thing you had to reject in order to be anybody at all.
What a man was actually wearing in 1934
To understand why the thing landed as it did, you have to know how unpleasant the alternative was.
The default undergarment of the early twentieth century was the union suit, a one piece knitted garment covering the body from shoulder to ankle, buttoned up the front, with a rear flap. It was warm, long, slow to get into and out of, and it bunched under the increasingly light and fitted clothing men were starting to wear. By the 1920s it was giving way to a vest and a pair of loose woven shorts.
But the loose short had a fundamental weakness, which is that it did nothing. It covered and it did not support. Under the increasingly athletic life men were leading, on bicycles and tennis courts and in gymnasiums, that was not enough. The only garment offering genuine support was the athletic supporter, and that was sports equipment rather than clothing, worn for the duration and taken off afterwards The Jockstrap Never Left the Locker Room.
There was, in other words, a hole in the market roughly the shape of a garment that supported like a jockstrap and could be worn all day like underwear. The knitting industry had also just acquired a genuinely new material in covered rubber yarn, sold under the trade name Lastex, which meant a garment could hold a shape against the body without a drawstring or a button.
A postcard, and an apparel engineer in Kenosha
The company that did it was Coopers, Inc., of Kenosha, Wisconsin. It had begun in the 1870s as a hosiery business founded by Samuel T. Cooper in Michigan, relocated to Kenosha around the turn of the century, and spent the intervening decades making respectable, unremarkable knitted underwear.
The design is credited to Arthur Kneibler, an executive who carried the wonderful job title of apparel engineer. The story every source tells, and which has the smooth quality of a story told many times, is that Kneibler received a postcard from the French Riviera in 1934 showing a man in a brief cut bathing suit, and recognised that the shape could work as underwear if given a functional opening.
Treat the postcard with the mild scepticism it deserves; origin stories of this kind are almost always tidied up in retrospect. What is not in doubt is the direction of travel. The garment that emerged had no legs at all, sat high on the hip, and used the new elastic to hold itself in place, and every one of those decisions points at European swimwear rather than at the American underwear drawer.
The genuinely original part was the front. Kneibler's construction ran two diagonal seams up from the base of the garment to meet a single vertical seam at the centre, with a separate panel of fabric lying behind the junction. The seams formed the shape of the letter Y lying upside down, which is where the name came from. The overlapping panel meant the opening did not gape, because the two layers were held closed against each other by the tension of the garment itself rather than by a button.
Every previous approach to a fly had been either a fastening, which is a thing to do up and a thing to fail, or a slit, which gapes the moment the wearer moves. This is neither. Closed by default, opened by hand, no moving parts. Coopers received a United States patent on the construction in August 1935 Anatomy of a Brief: Every Panel, Seam and Stitch Explained.
The blizzard, the window and the first day
On 19 January 1935, Marshall Field and Company put the new garment in a window at its State Street store in Chicago. The published accounts agree that the weather was appalling, a blizzard by most tellings, and that the store considered pulling a window display of men in minimal underwear as inappropriate to the conditions.
They left it up, and the garments sold. Accounts differ in a way worth being straight about: the company's own published history says more than six hundred pairs went before noon at fifty cents each, while Smithsonian Magazine has the store's six hundred pairs selling across the whole of that first day. Either way, a Chicago department store cleared its stock of an unheard of garment in a snowstorm.
The name was doing real work too. Coopers called the garment Jockey, with the stress on the first syllable in early advertising, precisely so the buyer would hear the word jock and understand what was on offer. The claim was masculine support, previously available only from athletic equipment, now available in something you could wear to the office. Later campaigns came at the same idea from the other direction, including one built around telling men to stop squirming, which is copy that only works if the audience already recognises the complaint.
The vocabulary of support, borrowed from the shoe shop
The 1930s were the high water mark of a particular kind of quasi orthopaedic consumer language. This was the era in which the ordinary man was sold arch supports for his shoes, trusses for his abdomen, posture braces for his back and elastic belts for practically anything. The vocabulary was medical without quite making a medical claim: things were supported, held, lifted, and the implication was that the unsupported body was slowly failing and could be rescued by a purchase.
The brief slotted directly into that vocabulary, sold as support rather than as style, in exactly the register used to sell an arch support. It is difficult to overstate how far that is from how the same garment would be sold fifty years later How Calvin Klein Sold Sex in 1982.
It also explains the colour. A garment sold as hygienic equipment is white, because white is what the medical and sanitary world looked like, and because white could be boiled Why Underwear Is White. A plain white cotton brief still reads, to most eyes, as the default white cotton brief.
Crossing the Atlantic, 1938
Britain got it three years later, and by a route that turned out to matter.
In 1938 the Scottish knitwear firm Lyle and Scott took a franchise from Coopers covering the United Kingdom, France and Holland. Lyle and Scott's own brand history records the internal reaction with some relish: moving from traditional knitted underwear to the cut and sew construction the Y-front required was thought reckless, and the company quotes Charles Oliver recalling that many predicted the collapse of the firm when production began at 27s 6d per dozen.
It did not collapse. The Y-front became one of the defining British garments of the next forty years, made at scale in factories at Gateshead and Dunfermline, the company's own account putting peak output at around 120,000 pairs a week.
The consequence of the licensing route is linguistic, and you can still hear it. In Britain and Ireland the garment is a Y-front, named for its construction, because that is what the licensee put on the box. In the United States it is a brief or a pair of Jockeys, named for the category or the brand. Two countries ended up with different words for one object because of a contract signed in 1938.
The default garment of the Western male
From the war until roughly the late 1970s, this was simply what men wore. Not most men: very nearly all men, across class and country and the entire English speaking world. It was the garment of national service and demob suits, of the works canteen and the golf club, of every father in every advertisement, sold in packs of three on every high street. It held that position for four decades with almost no competition worth the name Six Briefs That Built the Modern World.
Ubiquity of that kind is a wonderful commercial position and a terrible cultural one, because it makes a garment available as shorthand. By the time a thing is worn by everybody's dad, it means dad, and will go on meaning dad for as long as anyone remembers dads wearing it.
The fall, and what it was actually about
The decline is usually explained as fashion, and fashion is a real part of it, but the mechanism is more interesting.
Two things happened at once. The boxer short was successfully repositioned during the 1980s as the garment of the relaxed, confident, sexually plausible young man, a campaign of extraordinary effectiveness that took a garment with no support and no shape and made it aspirational Launderette: The Sixty Seconds That Rewrote Men's Underwear. And a schoolyard vocabulary attached itself to the brief in America and travelled, after which no amount of engineering argument was going to get it back.
There is a third factor specific to the Y-front rather than to briefs generally, and it is the fly. Men stopped using it. Somewhere in the second half of the century the habit dropped out of practice, and once nobody was using it, the seams became decoration, and decoration that signalled your father. Younger buyers moved to briefs with no opening at all, then to trunks, then to boxer briefs, and the construction that had been the entire point of the garment became the reason people avoided it The Great Rebrand: How the Boxer Brief Won the Argument.
The boxer short that displaced it also has a fly nobody uses, and gets no mockery for it whatsoever The Boxer Short Is a Pyjama.
The case for the defence
The overlapping front construction is, considered purely as engineering, better than what replaced it. It builds the front from separate shaped panels rather than asking one flat piece of jersey to accommodate a curve by stretching, which is the same principle continental makers charge a great deal of money for when they call it a contoured pouch Slip: Why European Briefs Fit Differently. The overlapping layer adds a second thickness of fabric exactly where a garment benefits from one. It holds a shape from the moment it leaves the machine rather than finding one on the body.
It also costs more to make than a flat front, which is the real reason it has thinned out at the cheap end of the market. Extra panels mean extra cutting operations and extra seams, and a supermarket multipack cannot carry them fine rib cotton brief.
The garment has quietly kept going, which people miss because they stopped looking. Jockey still makes it, and several European houses have never stopped making versions of the same idea. It sells steadily to men who wear it because it works and have no interest in the cultural argument, which is the healthiest customer base anything can have Y-front brief.
And the fly, unglamorously, still earns its keep. Anybody who has stood at a urinal in a full suit knows the alternative requires a less dignified manoeuvre. A garment that solves that with no fastening and no moving parts is not an antique. It is a solved problem we stopped noticing was solved.
Ninety years, and no cake
The honest summary is that this design has been in continuous production for ninety years, was copied everywhere, defined a category, gave two languages their word for the garment, and is currently mocked by people who could not describe how it is put together.
That is not a judgement on the design. It is a judgement on how much of what we wear is decided by what a thing signals rather than by what it does.
If you have never worn one, the experience is unremarkable in the best sense. A well shaped brief with a functional opening and a construction that holds up. It will not change your life. It is a piece of design that solved its problem, and kept solving it while the culture got embarrassed and moved on The Case for Briefs: Why They Should Be Every Man's Default.
Ninety years is a long run for anything. It deserved a better anniversary than silence.
Questions people ask
When were Y-front briefs invented?
Coopers, Inc. of Kenosha, Wisconsin first sold them on 19 January 1935 at the Marshall Field and Company store on State Street in Chicago, under the brand name Jockey. The design is credited to an executive named Arthur Kneibler and was patented in the United States in August 1935. They reached Britain in 1938 through a franchise held by the Scottish firm Lyle and Scott, which is why British English calls the garment a Y-front while American English calls it a brief.
Why is it called a Y-front?
Because of the seams. Two diagonal seams run up from the base of the garment to meet a single vertical seam at the centre front, forming the shape of the letter Y turned upside down. Behind the junction sits a separate overlapping panel of fabric, which is what makes the opening work without a button. The name describes the construction rather than the brand, which is why it survived into general use in Britain, Ireland and Australia for garments made by other companies.
Are Y-fronts still made?
Yes. Jockey has produced them continuously since 1935 and several European makers produce versions of the same construction. They occupy a small and steady part of the market rather than a fashionable one. The design is genuinely good: building the front from separate shaped panels rather than one flat piece of stretched jersey is what continental brands charge heavily for, and the overlapping layer adds thickness exactly where a garment benefits from it.
Why did Y-fronts go out of fashion?
Three things happened together. The boxer short was repositioned during the 1980s as the garment of the relaxed young man, an American schoolyard insult attached itself to white briefs and travelled internationally, and men gradually stopped using the front opening at all. Once nobody used the fly, the seams read as decoration that signalled a previous generation. The oddity is that the boxer short which replaced it also has a fly nobody uses, and attracts no mockery for it.
