Softball Piercing Rules?

I was wondering and couldn't find any info on if you cold have a nose piercing while playign softball. I have seen multiple people in tournament softball who wear eye piercings without penalty as far as im concerned because they still are allowed to play. If i were to put in a clear hole saver would that be okay? I live in pa and i need to know for school softball tournament softball and township softball. I have been playing softball for years and can never find the time off to get my nose peirced in an "off season" because i never have off (; so if anyone can give me some insight that would be awesome, thanks! also i play catcher and 3rd if that makes a difference, which i doubt it does. thanks!
