If that's you, I'd say don't do it. You've got a well put together vibe...a kind of serious, business woman, young but professional. Your face really doesn't seem like the kind of face that would take a piercing well.
They are cute, but not on everyone.
(I know a girl that's beautiful - like you - and she has a nose stud. It just looks off on her. She's too phlegmatic and serious in nature for it to work on her all that well.)
What kind of a personality do you have?
(believe it or not, this is also something you have to keep in mind)
