A question about embellishements

The embellishment of the body

I read an interesting blog post about tattoos, it gave me a new question to post on mine.

Some use tattoos, others piercings.  Jewelry or make up.  What is the meaning of some of those embellishments?
Do they have a personal meaning or are they there to explain something to others?  Do they use color or does the place where it is placed have another meaning?

Do your characters, have any embellishments and when, why and where did they get them.

I’m already thinking up stuff for my story!  How about you?
