Why Women’s Shirts Fasten on the Left — and Men’s on the Right: The Intriguing Story Behind a Common Daily Practice

Another theory connects the tradition to military customs. Historically, men often carried swords with their left hand stabilizing the sheath while the right hand drew the weapon. Clothing that overlapped from left to right helped prevent jackets from catching on weapons during combat. This practical design eventually became standard in men’s fashion.

There are also theories involving horseback riding. Women in earlier centuries often rode side-saddle, and left-fastening garments may have helped protect against wind exposure while riding. Although historians debate which explanation is most accurate, all of these ideas reflect how clothing design was once deeply connected to social roles and everyday life.
