ladies with nipple piercings

Olivia
I definitely want to get my nipples pierced but I had one question. How visible are they with clothes on. You see I'm 20 and still living with my parents (because it's cheaper) and they definitely would not like the idea. It's not that I would have to ask them for permission but I do live in their house so, they in a sense have some say on the things I do. What I was wondering is If I were to get them done are they only noticeable under shirts when you have no bra on?
