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. The stiffness of the garment forced upright posture, and their impracticality led them to become a symbol of wealth and status.

Now, it goes well every fit to add on playful elegant.
