Why Men’s Shirts Button on the Right and Women’s on the Left: A History of Which Way Clothes Close

Buttons themselves existed as decorative objects as far back as the Indus Valley civilization, but using a buttonhole to actually fasten a garment first appeared in 13th-century Germany.^[1] It’s often said that for centuries afterward, women’s clothing had almost no functional buttons. Surviving garments and paintings tell a slightly different story, though. Starting around the 1330s, clothing for both men and women in Europe became close-fitting, made possible by new cutting techniques and rows of closely spaced buttons.^[2] Some women’s outer garments from the early 15th century closed part of the front placket with buttons.^[3] Still, the front of women’s dresses in the 17th and 18th centuries was often fastened with pins or ribbon ties instead.^[4] It’s more accurate to say women’s clothing wasn’t buttonless, but that buttons were just one of several closure methods used at different times. This matters when weighing the popular explanations for why men’s and women’s buttons face opposite ways, because most of those explanations assume women’s clothing had been buttoned — in a fixed direction — since long ago.

Lay a men’s shirt and a women’s blouse side by side today, and the closures face exactly opposite ways. A note on terms: throughout this article, “which panel closes on top” is always described from the wearer’s own point of view — not as reflected in a mirror, but the direction you’d see looking down at yourself. By that standard, men’s clothing has its button sewn onto the right panel, with the left panel closing over it. Women’s clothing reverses this: the button sits on the left panel, and the right panel closes over it.^[5] Why the split? Carry the same question to the opposite side of the world, to East Asia, and you get a completely different answer — one where the line dividing closure direction wasn’t gender at all, but civilization, and even life and death.

For readers in the United States and Britain, the standardization story below has a familiar backdrop. By the 1890s, American department stores and mail-order catalogs — the same era that built retail names still recognized today, like Montgomery Ward and Sears, Roebuck — were selling identical, mass-produced clothing at a range of price points, letting shoppers buy a shirt or blouse off the shelf instead of having one cut to measure by a local dressmaker or tailor.^[25] The Smithsonian’s National Museum of American History notes that ready-to-wear clothing let Americans of different incomes dress more alike than ever before. That’s the same shift — standardized factory patterns replacing individual tailoring — that dress historians point to below when explaining how the men’s-right, women’s-left button rule hardened from a loose habit into a fixed convention that almost nobody questions today.

Taking the Popular Theories Apart One by One

Plenty of stories circulate to explain why women’s buttons sit on the left. The problem is that almost none of them are backed by primary sources.

The most widespread explanation is the “lady’s maid theory.” Wealthy women were dressed by maids, the story goes, and since most maids were right-handed, buttons were placed on the woman’s left so a maid standing face-to-face with her could fasten them more easily.^[6] It sounds plausible, but it has two weak points. First, as noted above, this explanation has little room to apply during the periods when women’s dress fronts were commonly closed with pins or ties rather than buttons. Second, wealthy men were just as often dressed by servants, and no one has explained why the same logic never applied to menswear.^[7]

For menswear, there’s the “sword-drawing theory.” Men wore swords or firearms at the left hip and drew them with the right hand, the argument goes, so jackets had to close right-side-under to keep the weapon from catching on the fabric.^[5][8] It’s physically plausible, but no dated record or tailor’s account has been found to back up the logic.

Two more explanations circulate for women’s clothing. One points to side-saddle riding — the style favored by noblewomen, in which both legs rested on one side of the horse — arguing the closure was reversed so wind wouldn’t blow into the garment. The other is a nursing-related theory: because women typically held infants in their left arm to keep the right hand free, buttons were placed on the left so the garment could be opened easily with the right hand.^[6] Both have their own internal logic, but neither has been proven for any specific era or region.

What all these theories share is that they’re plausible stories, not verified facts. Even the encyclopedia entry that lays out the lady’s maid theory concludes that “there appears to be no concrete reference to prove or disprove this story.”^[9]

So When Did the Opposite Convention Actually Begin?

So what’s left once the myths are cleared away? Dress historians generally see this as a convention that no one decided on a specific date — it hardened gradually, over the course of industrialization.

Start with menswear. In the 19th century, men’s clothing began to be mass-produced at uniform sizes in factories. In that process, the right-side button convention already common among male tailors hardened into a factory production standard.^[10] Women’s clothing followed a different path. There are surviving 18th-century examples of women’s clothes buttoned in the men’s direction. A women’s riding jacket from the 1750s in the collection of the Victoria and Albert Museum (V&A) was modeled directly on a man’s coat: it has 12 worked buttonholes on the left front panel, closing with the left panel on top — just like men’s clothing today.^[11] At least in this period, the case suggests the rule that “women’s clothing closes the opposite way” wasn’t yet fixed.

Experts disagree on exactly when the women’s convention hardened. Dress historian Robert Ossant places general standardization of button placement in the late 19th century, when clothing shifted from bespoke production to mass manufacturing.^[12] Fashion historian Chloe Chapin points instead to the 1880s, when styles that made women’s clothing resemble men’s became fashionable. Her hypothesis: since cross-dressing was illegal in many places, the difference in button direction may have served as a marker that a garment was women’s wear.^[8] Meanwhile, curators who work with 19th-century women’s clothing report seeing buttons facing both directions throughout the period, which has led some to argue that the women’s convention only settled once ready-to-wear clothing for women became widespread in the early 20th century.^[7] The three views differ somewhat on timing and cause, but they overlap in pointing to the same broad window: the late 19th to early 20th century.

To sum up: the practice of men and women closing their clothes in opposite directions may have existed in scattered form earlier, but it appears to have hardened into an industry-wide “rule” between the 19th and early 20th centuries — precisely when clothing started rolling off factory lines in bulk. No record survives of a single decision — who decided this, when, or why. What we can pin down is only the rough period of standardization; the origins before that remain uncertain.

East Asia’s Standard: Not Gender, But Civilization

Bring the same question to East Asia and the answer changes completely. In the traditional dress of China, Korea, and Japan, the direction a garment closed had almost nothing to do with whether the wearer was male or female. What it marked instead was which civilization the wearer belonged to — and whether they were alive or dead.

The basic principle of Han Chinese dress was youren (右衽) — the left front panel closing over the right. It’s an old convention, tracing back to the Shang dynasty and spreading across East Asia by the Tang dynasty.^[13] The reverse — the right panel closing over the left — was called zuoren (左衽), and was regarded as the style typically followed by the nomadic peoples on China’s periphery.^[13]

This distinction carried a heavy value judgment. The Analects, in its Xianwen chapter, records a conversation between Confucius and a disciple. Asked what would have happened had the statesman Guan Zhong not helped the state of Qi uphold the Zhou order, Confucius is said to have replied: “Were it not for Guan Zhong, we would now be wearing our hair loose and closing our robes to the left (微管仲, 吾其被髮左衽矣).”^[14] Here, zuoren stood for a collapse of civilized order — the customs of “barbarians.” Which direction you closed your robe, in other words, marked whether you placed yourself inside civilization or outside it.

But zuoren carried yet another layer of meaning. In traditional Chinese yin-yang cosmology, left is yang — associated with life — and right is yin, associated with death. The living were supposed to wear their clothes with yang covering yin, that is, in youren. Zuoren, where yin covers yang, was reserved solely for burial shrouds.^[13] Within Chinese culture, then, a single direction — zuoren — carried the meaning of “foreign custom” and the meaning of “death” at once. For a living Han Chinese person to wear zuoren was a double taboo.

The Japanese Kimono: A Line Between Life and Death

Japan inherited this convention wholesale. The Yōrō Code (養老律令), enacted in 718, stipulated that all robes follow the Chinese style, closing with the left panel over the right — the same direction as youren.^[15] The rule made no distinction by gender. Men and women wore their robes closing the same way, and that convention has carried straight through to the kimono of today.

There’s exactly one moment when this rule breaks in the kimono: when the wearer has died. The living wear the left panel on top without exception, but the white burial garment (死装束, shini-shōzoku) put on the deceased for a Buddhist funeral closes the opposite way, with the right panel on top.^[16] Even today in Japan, wearing a kimono closed the wrong way isn’t waved off as a simple mistake — it’s a taboo. People react with visible unease if they see someone wearing one that way on the street.

What’s striking is that this rule divides along a single line — life and death — and not gender at all. Unlike China, where zuoren carried the double meaning of “foreign people” and “death,” Japan had no threatening neighboring nomadic group to serve as that reference point. Perhaps for that reason, of the two meanings likely transmitted together from China, only the life-and-death axis appears to have survived clearly, while the ethnic distinction faded. This is, however, a circumstantial inference; no primary source has been found that states it explicitly.

The Korean Hanbok: Same Direction, Different Procedure — and One Exception

Korea’s case followed a somewhat more winding path. The closure direction of the jeogori wasn’t fixed from the start. There’s evidence of zuoren being used in early Goguryeo, followed by a period in which zuoren and youren were used interchangeably, before it was standardized to youren under Chinese influence during the Joseon dynasty.^[17] Today’s hanbok jeogori closes the same way for both men and women — left panel over right.^[17] At the level of everyday dress, in other words, there was no distinction by gender.

It was death, not gender, that split the direction elsewhere: in the burial shroud (壽衣, suui). Interestingly, Korea’s funeral procedure doesn’t stop at Japan’s simple binary. According to a history information site run by the National Institute of Korean History, during the early part of the yeomseup (殮襲) — washing and dressing the body — the shroud was put on in youren, the same way as the living.^[18] But starting from the soryeom (小殮) stage, when the body is wrapped, the direction changed. From that point on, the garment was closed in zuoren, the reverse of how the living wear it, to signify a complete severance from the world of the living.^[18] In other words, Korean funeral ritual split the single state of “death” into two further stages and marked the boundary between them with the direction of the garment’s closure. The Institute’s own commentary calls it “interesting that the boundary between life and death was marked by the direction of the garment’s closure.”^[18]

There is, however, one Korean garment where direction really does split by gender: the magoja, a warm outer layer worn over the jeogori. The magoja descended from the Qing-dynasty magwae (馬褂), and spread widely across the Korean peninsula from the 1880s, after Heungseon Daewongun brought the style back on his return from Qing China.^[19] Unlike the jeogori, the magoja doesn’t close deeply across the front; it’s fastened with a single button near the neck. That single button, though, sits in a different place depending on gender: on the right for men’s magoja, on the left for women’s.^[20] Why this particular garment, and only this one, ended up split by gender isn’t clearly recorded. The magoja took hold around the same time Western-style ready-to-wear manufacturing was just beginning to reach Joseon, which raises the possibility — whether by coincidence or some indirect influence — that it became entangled with Western convention in some way. No evidence has been found to confirm this, though. It has to be left as an open question.

Elsewhere, and Today’s Changes

In old Chinese thinking, zuoren was a marker for the nomadic peoples of the northern steppe. Yet look at the deel, Mongolia’s traditional dress, today, and something unexpected turns up: the deel closes with the left panel over the right.^[21] Direction-wise, that’s exactly the same as youren, the marker of “civilization.” The descendants of the steppe peoples that ancient Chinese rhetoric singled out as the “zuoren barbarians” are, at least today, closing their clothes in exactly the same direction as that “civilized” marker. A single example like this can’t be extrapolated all the way back to the actual dress of the ancient Xiongnu or the Mongol Empire, of course. Dress may have changed more than once over the centuries, and the very category of “zuoren barbarians” may have owed more to Chinese rhetorical stigma than to real observation in the first place. Either way, the case suggests that the meaning attached to a direction was less a fixed ethnic identity than a label that shifted over time.

Even the Western convention that used gender as its dividing line is wobbling today. Consumer demand for gender-neutral fashion is growing fast, and more brands are launching lines designed with no gender distinction from the outset, like Zara’s “Ungendered” collection, which it rolled out in 2016.^[24] In a 2022 survey of roughly 12,000 consumers across 11 countries, 36% of U.S. respondents said they had already bought clothing classified outside their own gender.^[22] The trend is sharper by generation: in the same survey, roughly one in two Gen Z respondents had already bought clothing that crossed gender lines. Across all respondents, seven in ten said they wanted to buy more such clothing in the future, an intention that grew stronger with each younger generation.^[22][23] A rule that took centuries to harden is, in this generation, being taken apart again.

The Rule Remains, the Reasons Scatter

Pull back, and one curious coincidence stands out. The Western men’s direction — left panel over right — is structurally identical to youren, the direction China treated as a marker of civilization. The Western women’s direction — right panel over left — matches zuoren, the direction China treated as a marker of “foreign peoples” and of death. The two traditions never had any contact, of course, so this isn’t a case of influence — it’s a purely structural coincidence. But the coincidence makes one thing clear. Whether a garment’s left panel or right panel ends up on top is, by itself, meaningless — a binary choice with nothing riding on it. Meaning is something people lay on top of that binary.

The West laid gender on top of that binary. The grounds for it turn out to be surprisingly thin, and it standardized far later than most people assume — during industrialization, not antiquity. China laid the boundary between civilization and barbarism on the same binary, and stacked the boundary between life and death on top of that. Japan kept only the life-and-death boundary and let the rest fall away. Korea erased the boundary entirely in everyday dress, only to carve it more finely within the ritual of a funeral. And the small exception of the magoja shows that even within a single culture, a different garment can generate its own new rule at any time. That such different stories have piled up around the very same two directions is itself the point: this seemingly trivial custom turns out to be a mirror reflecting how each culture has drawn its own lines around itself.
