We've had quite a few "tattoo" threads since the inception of GN. Quite understandable, if you are fairly new, you wouldn't haven't seen previous ones. As always they divide opinion, I'm constant in mine, I really dislike them. One of my sons has a couple.
Each to their own, I think they really spoil lovely limbs, toned arms and legs don't need writing on them at best they look grubby at worst sometimes they look like bruises. I remember the late Peaches Geldof and Amy Winehouse both had loads, sometimes that suggests "an out of control/addictive" personality to me, they were both attractive girls, they'd have looked so much better without them imo. Angelina Jolie is another and hers look all wrong when she wears an evening dress, why would you want the geographical co-ordinates of where your children were born plastered up your back for someone else to puzzle over. Kind of useless information anyway
Bodies sag and droop and become wrinkly as they age, the inkings on wrinkles and saggy bits are going to look a bit sad one day
