Because most people are right-handed, buttons positioned on the wearer's left side would be easier for a servant standing opposite to fasten.
Historians believe this practical consideration eventually became a standard feature of women's clothing.
Over time, even as fewer women relied on servants, the convention remained part of fashion design.

Some historians believe women's button placement originated from a time when wealthy women were dressed by attendants.
Why Men's Buttons Ended Up on the Right
The explanation for men's clothing is often linked to practicality and military traditions.
Most men were right-handed, particularly soldiers and hunters who frequently carried weapons.
Placing buttons on the right side made it easier to open garments quickly with the dominant hand while accessing a sword, firearm, or other weapon.
Military uniforms were designed around these movements, and many clothing traditions eventually spread into civilian fashion.
Experts note that button placement likely became standardized because it complemented the natural movements of right-handed wearers.
The Influence of Military Culture
Throughout history, military uniforms have influenced everyday fashion.
From trench coats to tailored jackets, many common clothing designs originated from military needs.
