A very short (often only 12" long) skirt. Micro minis are often considered both sexy and slutty. Became popular, particularly with high school and college age women, during the late 1990s-early 2000s.
A woman who is only moderately attractive will turn heads and get noticed if she wears a micro mini.

Miniskirts shouldn't be allowed in middle school let alone microminis!
