A hair shirt is a coarse garment intended to be worn next to the skin, keeping the wearer in a state of discomfort and constant awareness of the shirt's presence. Such garments were traditionally worn by some Christian religious orders, along with individuals who felt penitent about certain actions or their lifestyles. Their use is fairly limited in the modern era, but the term is often used metaphorically, which is why someone might refer to "wearing a hair shirt" when they perform some other act of self-imposed penitence.

Originally, these garments were known as cilices, in a reference to the Latin word cilicium, meaning “covering made from goat's hair.” Early shirts were made from sackcloth or coarse animal hair so that they irritated the skin, and later versions integrated additional uncomfortable features such as thin wires or twigs. Several characters in the Bible wore hair shirts as demonstrations of religious faith, and the practice was picked up by devout members of society and the Church. The term “cilice” is now used more generally for any object worn to increase discomfort.

The tradition of wearing hair shirts is part of a practice called the mortification of the flesh. Mortification ranges from a simple denial of pleasures to actually committing serious injury, as in the case of medieval flagellants who whipped themselves during the time of the plague. This is said to be an expression of faith, and it is also meant to train the soul, expelling sin and promoting pious, faithful behavior. Extreme mortification is no longer in vogue in most Christian sects, but more mild forms, like fasting, are an important part of religious faith for some devout Christians.

Religious ascetics often engage in mortification to bring themselves closer to God, and to keep their own religious practice humble. In the era when these garments were a popular form of mortification, many others in society ranging from kings to merchants wore them. Members of the upper class engaged in mortification to encourage themselves to be mindful of God, and sometimes to do penance for decking themselves out in fine clothing. The shirts were usually worn under other garments, because showing one off would be a form of vanity, punishable by additional penances.

While the concept of a hair shirt may seem archaic or repugnant, awareness of suffering is an important aspect of many religions, from Buddhism to traditional shamanistic practices. Since these garments are worn as a form of voluntary mortification, they should not be considered in the same category with acts of torture and forced penance.

I think it would be more effective if Wall Streeters wore a hair jock-strap -- or maybe twigs or wire.

All bankers on Wall St should be required to wear hair shirts for 40 days.

Many saints wore them. Even modern day saints such as Padre Pio, and Mother Theresa.

@mitchell14 - That's true, although as the article says there are many forms of lesser penance, especially in Eastern traditions. Buddhism, Hinduism, Islam and Judaism all involve fasting on holy days to some extent, and many of these traditions have some sort of dietary restraint as well. I suppose in modern Christianity, Lent would be an example of the remaining penitential tradition.

This idea of voluntary penance is really interesting, I bet the shirts would have gotten very hot too, making them almost unbearable. It also makes me think about the lack of voluntary penance in many religions today.
