jewelry;how much is too much?

[Little Jimmy]

I started doing womens' adult fast pitch last year (ASA rules),the new season starts next week and I'm curious about something. The women seemed to be able to wear just about anything (multiple earrings, necklaces, etc.)without any ump saying anything. It was a couple of games into last years' season before I got a plate duty and by that time I was just following the example set by all the other umps. I always felt a little wierd letting a player with a 3 studded ear(yes I could see them through the helmet hole)and two necklaces stand at the plate but my partners said that's the way it was done in this league.
What's your feeling and do you have a limit? I'm coming off a Fed high school season where all visable jewelry was a no-no. ASA 3-6-F seems to leave it up to the ump. Opinions?
