Law firm open day advice

Hi there,

I've got a place on the open day of a law firm tomorrow.

This might seem like a silly question, but I'm a guy and I've got 5 piercings, 3 in my lobe and then 2 in my upper ear. They're all quite subtle (golden hoops) and most people don't even notice them. I was wondering if I should take these out for the open day and any other sort of work thing in the future, as I feel I've heard people say stuff like that is unprofessional?

I spoke to a friend about it and he told me to keep them in because they make up who I am etc etc

Any advice?

Thanks so much
