Hmmmm. My husband is a vice president at a Fortune 20 company - at age 36. Last count he has 13 tattoos. None visible in standard business attire, but the higher ups have known he has a bunch for a long time. At his previous job, his boss knew of his tattoos (and a tongue piercing he’s since removed at my request) prior to hiring him.
“None visible in standard business attire.”
I think that’s the key aspect to most employers.
