I think done well tattoos can look awesome and it’s an individual choice.
The tattoos you see fresh and vibrant with beautiful colours though mostly fade and the black turns a blue colour, the outline is usually never as sharp as it originally was years later.
As I mentioned in my pp, there is a trend currently for the full neck tattoo and despite not wanting to think negatively towards a woman getting one, the first thing I always think is, I hope you don’t regret that, especially when I see a young woman in her 20’s. Men can easily disguise by growing a beard/stubble, on a woman it’s a much starker contrast.
DH has tattoos so I’m not against them but his are easily hidden and not permanently on show. If DS chose to have a tattoo in the future, I would at least make sure he researched the tattoo artist thoroughly, making sure they were experienced in the type of tattoo he wanted (just as my DN did, she travelled a distance for her tattooist) but ultimately it would be his decision. I would rather be involved in the process with him though than going against it.
Each to their own but I’m still on OPs side here, she has a right to feel the way she does, no one has the right to tell her the way she should feel.
