Pinafore
(重定向自Pinny)
A pinafore (colloquially a pinny in British English) is a sleeveless garment worn as an apron.
Pinafores may be worn by girls as a decorative garment and by both girls and women as a protective apron. A related term is pinafore dress (known as a jumper in American English), i.e. a sleeveless dress intended to be worn over a top or blouse. A key difference between a pinafore and a jumper dress is that the pinafore is open in the back. In informal British usage, however, a pinafore dress is sometimes referred to as simply a pinafore, which can lead to confusion. Nevertheless, this has led some authors to use the term "pinafore apron", although this is redundant as pinafore alone implies an apron.
