Do it! Looked at your picture, you've got a good nose and you'll be able to pull it off. Also, It doesn't hurt a bit, doesn't swell and doesn't hurt after! best piercing to get and I've had pretty much every piercing under the sun and my nose hurt the least, I even did it myself. Good luck! x
I think it makes you a typical teenager that has no idea what she's doing or any idea who she is and is just out to fit in with the cool kids. do you think you're going to want it in a few years? not a chance. so just don't do it. it's a waste and is likely to send the wrong messages to others.
I got one for my birthday last year. It was pretty painful >.< and expensive. Just for the stud itself it was like $60. Not to mention, a month after I got it, I lost the stud (it fell down the drain D:) and my hole closed. But anywho, if you do decide to get one make sure you clean it everyday, at least 3-4 times with warm water and sea salt. You can use a q-tip to clean it, it's a lot easier
