A miniskirt is a skirt with its hemline well above the knees, generally at mid-thigh level, normally no longer than 10 cm (4 in) below the buttocks; and a dress with such a hemline is called a minidress or a miniskirt dress. A micro-miniskirt or microskirt is a miniskirt with its hemline at the upper thigh, at or just below crotch or underwear level.
