I have a very dainty, tight hoop in my ear cartilage. You wouldn't even notice it, probably.
Unless you are a 5th grade girl. I was told by one today that she loved my top ear ring. She plans on getting one when she's 15. When I suggested that she wait until she's older, she informed me: "Oh, no! When I'm 16, I'm getting my belly pierced."
