I have already commented on this in the Ukraine thread, there was a short film of Ukrainians training in the UK and one of the instructors was a young Canadian female office with flower tattoos on her neck and I stated then how refreshing it was to see that old rule had gone. Offensive items, yes I agree shouldn't be visible, but the rest why not, we are no longer living in the middle ages.
Incidentally, I remember watching a programme ages ago about cosmetic tattooists and what they do is spectacular, they re-colour items like burns, scars or birthmarks to make them look like normal skin, heck they even add nipples on women that have sadly had to have a mastectomy to give them back a sense of normality..
