I would put a bet on it that they are jealous - would never have the courage to do it themselves - so knock others that do.
I have not long had one done and i loved it and i did tell my family and friends, i even put one or two on FB some of the less revealin ones. I had amixed reaction, some said Wow and others didnt approve.
I feel sorry for them that feel that way but dont ever regret or feel bad about doing something like that - you go girl xx
I get married on 27th August xx
