The only appearance rule I can think of is when you should and should not wear your badge/pin...i.e. you don't put your badge on a t-shirt or a sweatshirt, or any top when you're wearing jeans.

Tattoos and body piercings are so common now I can't see how you could enforce any rule on those these days. I wouldn't get one (although my mother in law has several tattoos!)...I'm way too conservative for that....but I've come around to accept the idea that girls and women can have a tasteful, discreet tattoo and nobody really cares.

but the dermatologist/plastic surgeons in the office next door to mine are making a fortune doing tattoo removal and reconstructive surgery on piercings gone wrong!
