The ruff, which was worn by men, women and children, evolved from the small fabric ruffle at the neck of the shirt or chemise.
Ruffs served as changeable pieces of cloth that could themselves be laundered separately while keeping the wearer's doublet or gown from becoming soiled at the neckline.
Later ruffs were separate garments that could be washed, starched, and set into elaborate figure-of-eight folds by the use of heated, cone-shaped goffering irons.
The ruff was banned by Philip IV of Spain in 1621 in a symbolic attempt to reduce the inertia and power of the conservative Spanish elite.
The Church of Norway removed the ruff from its clergy uniform in 1980, although some conservative priests, such as Børre Knudsen, continued to wear them.
According to some of Anne's contemporaries, she wore a yellow ruff to her trial, after which the executioner ironically decided to wear the same colour to carry out her sentence.
