From Undershirt to Everyday Fashion
T-shirts were not always worn as outerwear. Originally, they were mainly used as undershirts. Workers, sailors, and soldiers preferred them because they were lightweight, comfortable, and easy to wash.
Over time, people began wearing T-shirts on their own. They gained popularity because they were practical and affordable. A T-shirt could be worn while working, relaxing, exercising, or spending time outdoors.
By the mid-20th century, the T-shirt had evolved into more than just a basic garment—it became a staple of casual fashion.
