A Brief History: From Underwear to Icon
1. The Early 1900s: The Utility Uniform

T-shirts gained popularity among laborers and farmers in the United States because they were practical, comfortable, and cool in the heat. However, it was during the early 1950s that they began to transcend their status as mere undershirts.
This transformation was largely attributed to iconic figures like Marlon Brando in A Streetcar Named Desire (1951) and James Dean in Rebel Without a Cause (1955).

Suddenly, the T-shirt wasn’t just underwear; it was a symbol of rebellion, youthful coolness, and rugged masculinity.
