Miniskirt
From wipipedia.org
A miniskirt is a very short skirt (using "mini" to mean very small). Classically, if you are standing erect then the skirt should be so short that you can reach the hem with your middle fingers. The shortest skirts are sometimes called microskirts.
History
The term is first recorded in 1965. Mary Quant, a fashion designer, is said to have named, and sometimes invented, the miniskirt. André Courrèges was a French designer who also produced miniskirts at about the same time as Quant.
