28 year old professional here! Full sleeve, both feet, back, left side and thigh and right ribs.
Partner is also a professional, he's also got a full sleeve.
I work as a project manager and have done for the last 5 years. When I started my career I made sure every tattoo I had was easily covered as they're not everyone's cup of tea and there's still a stigma around them. Fortunately my company embrace individuality and believe the company should represent its staff. Within my close team there are three of us who are heavily tattooed and our clients love it! For new clients I cover up out of respect but once that relationship is maintained then cover ups stop.
There is also a lady who works in finance who has bright red hair, a face full of piercings and is also covered in tattoos.
Not once have they ever hindered my career path.
My partner and I live an alternative lifestyle. We love festivals, gigs, rock music that sounds like the devil when played backwards and sacrificing goats in the street ( ;) ), but we have a heart of gold. We're thoughtful, honest people and we work hard to pay our bills and ensure we can provide ourselves a good life. If I ever have kids then I pray to God they embrace an alternative lifestyle over a chavvy one. When do you ever hear about mini Goths stealing cars and mugging old people? At the end of the day all that will matter is that they're a good person.
OP I know you worry about your daughter and the effect it will have on her life but also remember the world is a changing place and tattoos are more widely accepted now. Like others have said, she's still your daughter - tattoos don't come with personality changing ink - so please don't look at her skin, look at her heart.
