OP it's more than fine that earrings are ok, I myself have my ears pierced 3 each side, on practice i only wear one stud and a hoop on my left, but I also have visable tattoo's. As for nails they do have to be short and clean, i feel jealous towards girls who have lovely long manicured nails, but i'd rather have clean nails than long ones which have loads of yucky stuff inside! I do however wear different studs, never plain, like musical clefs..smily faces, a bit of variety and patients always ask which pair i'm wearing today. Oh and my hair although it's dyed anyway, it currently does have pink underlayers lol
