Some of the most outrageous beauty standards are portrayed in Body Piercings, ranging from simple rings or studs to extremely bizarre and painful items (such as barbed wire or chair legs). Piercings are also done to almost every portion of the body in various cultures, as well as done into patterns to reflect various cultural practices or beauty standards.
What is interesting however is that piercings are something that is placed within the realm of beauty standards in many different cultures around the world. This leads us to question if there is some basic aspect of body piercing which humans find attractive, something that is governed by genetic programming and perhaps modified in variety and appearance based on cultural practice. In essence, there seems to be a strong correlation for an instinctual behavior behind why we may find body piercing attractive. Items that are used in piercing or gauging, as well as where on the body they are located would then be dependent upon parts of the body which are accentuated by the culture.
This can demonstrated by examples such as the one below

Obviously the idea is that the piercing appears as the back of a corset (corsetry as well being a more extreme beauty practice). This can also be seen in other cultures in which it becomes a competition for who can have the largest gauges or most ridiculous or painful items as possible.
This is a prime example of the nature-nurture debate that occurs in developmental psychology, as well as the basis in which drives out attraction for mate acquisition.
I found this a very interesting thought! While I personally find a lot of the more extreme piercings very odd, I can definitely agree that many cultures around the world, both primitive and advanced, place value on some sort of attractive value on these.
In regard to the corset piercing: why would you get that? It just looks so painful! However, I guess because wearing corsets has been done to make people more attractive, this piercing may drawn on that feeling in the people who see someone with this.
