Hi!
I work in a profession (nursing student, hospitals, nursing homes) where tattoos are typically frowned upon. I do have one on my wrist, however, on the side, not on the underneath of it. (

For work, I have a watch with a slightly thicker band that covers it. For interviews I always wear long sleeves. I also have a cute thick bracelet that covers it as well.
I think you just need to balance what is possible and suitable for your lifestyle - but without compromising your individuality and creativity too much.
