I have my ears pierced twice and the lower holes are gauged to double zero. That's about as big as your pinky. The only other ones I have are a labret and my belly button. If you are pretty, too many piercings take away from it. Also, it depends on the structure of your face what rings look good. If you have tiny thin lips, lip rings are not good. If you don't want the whole metal/ goth look, try a little nose stud.
Tip: If you really aren't sure. Get a couple fakes. Get a fake stud, the ones with magnets, and get a spring-loaded ring. They sell them at Claire's. Wear them around for awhile, trying them on new spots each time. (It's hard to do this on eye-brows.)
Few piercings, big hair. Hair can always be changed if you don't like it. ^-^
