My observations are different from the other postings. I have seen female doctors, lawyers, business owners and supervisors. Double piercing is a long established acceptable fashion. Just look around; multiple piercings are worn by many people in the business and professional work forces.
Lol me. But I don't wear both set.
I know a few, but none of them wore both sets of earrings for their interviews, and I don't think I've ever seen them wear them to work either.
No, because if they got a double piercing when they were younger, they just put an earring in one of the holes and leave the other one empty when they go to the office!! : }
