A microskirt or micro-miniskirt is a very short skirt, being shorter than a miniskirt, being less than 8 inches (20 cm) in width. The microskirt is sometimes humorously referred to as a beltskirt and is described as more an evocation of the idea of a skirt than something that covers anything substantial.
At that width, if the wearer has bare legs, the microskirt exposes the thighs and the lower portion of the buttocks, as well as part of the underwear, with even more being exposed if the wearer bends down. To avoid exposure of buttocks and underwear, a microskirt may be worn with tights, leggings, shorts or bloomers. They are predominantly worn by teenage girls or young women to evoke an impression of cheekiness and playfulness, especially when accompanied with appropriate body language and in an appropriate social context. Stretch microskirts may be made using spandex material which may be worn by the more daring in conjunction with hold-ups and a pair of stiletto heel pumps, and sometimes with G-string underwear.
Microskirts are rarely worn as streetwear. They are commonly worn by cheer girls and often by singers and entertainers during performances, such as by Fergie, Micky Green, Beyoncé Knowles and others. They have also on occasion been worn without controversy by celebrities, such as Gwyneth Paltrow. Miniskirts were very popular in Japan, where they became part of school uniforms, and microskirts came to be worn within the kogal subculture  and by young girls practising panchira, a form of exhibitionism. Microskirts are also common among strippers working the floor inside a strip club.
The microskirt appeared in Europe in the late 1960s following the popularity of the miniskirt made famous by designers such as Mary Quant. Early version of that period were merely shorter patterns and allowed rather more exposure of the thighs of the wearer. Shorter versions started becoming available and some were quite short, having the hem at about the top of the thighs, often providing a glimpse of underwear. By the early 1970s the microskirt was less favoured, the 'Hot Pants' having become popular.
The microskirt became common on European catwalks after 2000, especially after Tom Ford, the stylist at Gucci, made a statement in September 2002 forecasting that microskirts will feature in the spring/summer 2003 collections."
