​The placement of buttons on men’s and women’s clothing—right for men, left for women—is a subtle yet enduring distinction rooted in historical practices and societal norms. While the exact origins remain uncertain, several theories offer insights into this sartorial divergence.

​

One prevalent theory suggests that the differentiation dates back to the 13th century when buttons were a luxury item, primarily adorning the garments of the wealthy. Affluent women often had maids to assist them in dressing; positioning buttons on the left side made it easier for right-handed maids to fasten them. Conversely, men typically dressed themselves, so buttons were placed on the right side for the convenience of right-handed wearers. ​

Another perspective ties the button placement to men’s historical use of weaponry. Men commonly carried swords on their left hips to draw with their right hands. Having garments that buttoned left over right reduced the chance of the sword catching in the clothing during a draw, leading to the standard of right-side buttons for men.

Additionally, some historians propose that as women’s fashion began incorporating masculine elements in the 19th century, maintaining opposite buttoning served to distinguish women’s garments from men’s, especially during times when laws prohibited women from wearing men’s clothing. ​

Despite the evolution of fashion and societal norms, the tradition of gendered button placement persists, reflecting a blend of practicality, historical customs, and cultural distinctions that have shaped clothing design over centuries.
