At this point, a reasonable question appears:

If the original reasons behind the difference are uncertain, why haven't clothing manufacturers simply standardized buttons on the same side for everyone?

The answer has a lot to do with tradition.

Fashion is not purely about engineering. If it were, many garments would probably look very different from the way they do today.

Clothing communicates identity, social expectations, occupation, formality, and sometimes gender. Small construction details can become part of those conventions.

Once consumers become accustomed to men's shirts having buttons on one side and women's garments having them on the other, manufacturers have little reason to change the system.

Imagine buying a familiar shirt and discovering that the buttons suddenly appeared on the opposite side. The shirt would still function perfectly well, but it might immediately feel unusual.

That feeling of "something looks wrong" is important in fashion.

Design conventions create visual expectations.

The same principle applies to pockets, collars, cuffs, trouser construction, jackets, and many other clothing details. People become accustomed to particular patterns, and designers often preserve them because consumers recognize them instantly.

There is also a practical manufacturing issue. Clothing production operates through established patterns and supply chains. Changing a standard design across an enormous industry would provide relatively little benefit while potentially creating confusion.

Modern fashion does occasionally break these conventions. Unisex clothing, experimental designs, asymmetrical shirts, wrap garments, and alternative fastening systems can place buttons wherever a designer chooses.

Some modern garments even abandon buttons entirely in favor of zippers, snaps, magnets, hooks, or other fasteners.

Yet traditional button placement remains common because it has become part of the visual language of clothing.

So, when you button a shirt, you are participating in a convention that has been shaped by generations of fashion.

The detail may seem insignificant, but it demonstrates something fascinating about design: once a convention becomes familiar, people often continue using it even when they no longer remember why it began.
