Brunette Girl Reveals Her White Pinafore And Hold-ups With Garter Belts Suspenders At The Window On The Sofa Chair

In modern times, the term "pinny" or "pinnie" has taken another meaning in sports wear, namely a double-sided short apron, often made of mesh, used to differentiate teams. This usage is chiefly British, with some usage in Canada and the United States. This type of pinny is also known as a scrimmage vest.
History
The pinafore was a type of apron that was pinned over the dress and easily removed for washing. Buttons were frequently damaged with lye cleaning products, which was one reason why dresses were not laundered very often.
