Cute Young Brunette Girl Reveals Her White Sleeveless Shirt On The Chair

In places like Venice Beach, Miami Beach bodybuilders used to take regular t-shirts and rip them by hand, forming improvised tank tops. The result was a shirt that allowed them to watch their muscles in the mirror as they worked out and provided plenty of unrestricted freedom of movement.
• Sleeveless T-shirt
A sleeveless T-shirt, also called a muscle shirt and colloquially called a shooter shirt by basketball players, is the same design as a T-shirt, but without sleeves. They are primarily worn by men since the large open sleeve holes would expose the female breast under certain circumstances. They are often worn for/during athletic activities. They were quite popular in the 1980s and were stereotypically associated with surfers and body-builders (hence the name "muscle" shirt) who often bore the logo of their gyms on these shirts. Also called "Tenement T-shirt".
