Iconic T-shirt, the essential casual wear
A classic cotton T-shirt reminds us of one of the survival principles: Three is two, two is one, and one is none. This principle refers to duplicating equipment because, in extreme conditions, good preparation is the key to survival. The distinctive shape of T-shirts evolved in the early 20th century from the previous underwear (known as a union suit). After World War II, cotton T-shirts in the shape of the letter T became very popular, partly thanks to Marlon Brando and James Dean, who wore them on screen.
