I don't have any tattoos as I think they look a bit iffy on women. I saw someone the other week who must have had one on her upper arm years ago and her skin had sagged and the tattoo had become quite defaced and looked quite stupid.
I am sure if there was a problem with the ink the tattooist would have experienced problems themselves.
What is the tattoo going to be of?
These slim women seem to carry a small tattoo well but I don't think they would look good on me http://www.vanishingtattoo.com/top100_women_tattoos.htm
