Hi
First of all I don’t think the idea is dumb – I have seen many pin up girl tattoos that are well depicted and look well on the person. (Personally not my thing but brings me to my next point).
It doesn’t matter what we think – it is your body that it is going on. You have to ask yourself – do I really really, really, want this tattoo?
I say this as first tattoos are an important decision as they are going to be on your skin for life – unless you go for a cover up or painful removal.
My suggestion is really take your time on the design and look at it everyday for a month and think do I still like this? If you do – go for it. If not choose something else or leave it.
Others may say I am talking bollocks but I always argue better to be cautious and happy than rushed and pissed off.
Good luck
Matthew
