I don't think you are ever to old to have your nose pierced. I think they look great no matter what your age.

I had my nose done when i was 14 and my labrett (chin) done when i was 16. I took my nose out when i was 17 though as i thought that have both in might be a bit too much. I still have my labrett done though. I sometimes wonder wether there will be a time when i should take it out. But i love it so much that i don't want too!
