When you open your wardrobe, one of the most common and versatile clothing items you’ll find is the T-shirt. From plain white tees to graphic prints and branded collections, T-shirts have become a global fashion staple. But have you ever wondered — what does the “T” in T-shirt actually stand for, and where did it come from?

Let’s explore the origin, history, and evolution of the T-shirt, uncovering how it became one of the most iconic garments in modern fashion.

The Meaning of the “T” in T-Shirt

The “T” in T-shirt simply refers to the shape of the garment. When laid flat, the shirt resembles the letter “T,” with its vertical body and horizontal sleeves forming a distinct “T” shape.

Unlike buttoned shirts with collars, cuffs, and more complex tailoring, the T-shirt was designed with simplicity:

• A straight torso
• Short sleeves that extend outward
• A round neck (crew neck) or V-neck design

This practical design gave the T-shirt its name, and the term stuck globally.

Early Origins of the T-Shirt

1. 19th-Century Underwear

The T-shirt’s history can be traced back to the late 19th century. It was originally worn as an undergarment. Men, especially laborers, found the design practical and comfortable during physically demanding tasks.

• The U.S. Navy adopted a similar style of undershirts in the 1890s, made of lightweight cotton.
• These shirts were collarless and could be easily worn under uniforms.

2. Transition into Everyday Wear

By the early 20th century, workers, miners, and farmers in the United States started wearing the T-shirt without any upper garment, especially during hot summers. Its comfort and breathability quickly turned it from underwear into casual outerwear.

T-Shirts in Popular Culture

The real turning point for T-shirts came in the mid-20th century, when they shifted from being basic garments to cultural fashion statements.

• 1930s: The word “T-shirt” first appeared in Merriam-Webster’s Dictionary.
• 1940s: Soldiers returning from World War II popularized T-shirts as casual clothing.
• 1950s: Hollywood made the T-shirt iconic. Stars like Marlon Brando in A Streetcar Named Desire (1951) and James Dean in Rebel Without a Cause (1955) wore plain white T-shirts, symbolizing rebellion, youth, and masculinity.
• 1960s–70s: T-shirts became a medium of expression. With the rise of screen printing, they carried slogans, band logos, and political messages.
