I have tattos from the wrist up and below my neck, but I invest in long-sleeve shirts. Personally, I think a long sleeve shirt with a tie looks more professional than a short sleeve with a tie anyway, so I really had no problem deciding to get tattoos that cover my arms. I also know two people who wear suits to work everyday but are covered completely below the neck minus the hands.

It all depends on what field you are getting into, and what type of clothes you will be wearing to cover up if need be. A tattoo on the wrist is easily hidden by long sleeves.
