SAEDNEWS: The right-side button placement on men’s shirts is largely linked to historical clothing traditions, military dress, and the practical habits of earlier wearers.
According to SAEDNEWS, the buttons on most men’s shirts are placed on the wearer’s right side, while the buttonholes are on the left. This small detail may seem arbitrary, but it reflects centuries of clothing conventions rather than a simple rule about comfort or appearance.
One widely cited explanation connects the arrangement to historical European clothing, particularly garments worn by men who commonly dressed themselves. Having the buttons on the right side may have made fastening easier for right-handed wearers, although historians do not consider this explanation completely proven.
Another important influence was military clothing. Uniforms developed standardized fastening systems, and right-over-left arrangements became common in many styles of men's clothing. As tailoring traditions evolved, these conventions were gradually carried into everyday shirts and other garments.

The contrast with traditional women's clothing is particularly interesting. Women's garments have historically tended to place buttons on the opposite side. Several explanations have been proposed, including differences in dressing practices among wealthy women in earlier centuries, when garments were sometimes fastened by attendants.
However, the exact origin of the distinction is not fully established. The commonly repeated explanations are historical theories rather than a single documented event that definitively created the convention.
Today, the placement has little practical importance. Modern shirts are manufactured according to established design standards, so putting buttons on the right for men's shirts immediately signals a familiar garment style.
The convention persists mainly because clothing design is strongly influenced by tradition. Once manufacturers, tailors, and consumers become accustomed to a particular arrangement, there is little reason to change it.
So, the right-side buttons on men's shirts are not the result of one clearly documented invention. They are better understood as the product of historical clothing practices, tailoring conventions, and traditions that continued from one generation to the next.
