How unprofessional is it to have double studded ears? (See description)

It’s just that I love piercings and I’d love to get a second hole pierced on each ear. My parents are against it claiming that only “bad girls” pierce their ears like that.

I have fake earrings which I use as an alternative way to have double piercings and before an interview I had my father was like “you must go formally and polished and don’t forget to take those piercings off your ears”. I mean, if they’re what I like, then why shouldn’t I have them?

I asked my mother what would she do If I had them done, and she was like “I’ll send you out of this house”.

I’m really urged to go and have them done NOW but I’m afraid that when my parents find out I’ll be dead...
