Both ears... only one ear would be awkward... and it will close up again if you don't wear something everyday0

I think piercing both looks more elegant. I think only having one looks okay, but not very professional. But I guess it's a fashion statement. Just don't expect everyone to like it if you choose to do it.
I guess as long as you like it it doesn't really matter though.0
