Angelina next year 🙂 although i'm generally not a fan of tattoos, i wouldn't need a ban from my father for that, but i'd like to have a belly button piercing
the washable tattoo was just an experiment to see how it would look on me. Not as bad as I thought but a real, no! (Except maybe the names of my children later)
I agree that a belly button piercing would be the best choice for you..
You can try to discuss it with him again and if it is necessary to "exchange" something ( rules, tightband, bra, anything) with him to let you get it
I think you can convince him if you really want it.. 🙂
There are also belts that can be worn without cause a problem to your belly button piercing 😉
