I've seen at least one of the models sporting small tattoos in the past, and at least one of them is still appearing regularly on QVC.
Today there are increasing numbers of people with extensive tattoos, so I think it's just something we all have to be prepared to get used to seeing in any walk of life.
Initially anything "different" is distracting and a primary point of focus... but as you get to know a person with a distracting feature you stop focusing on that and focus on them as a person. It's more difficult with people on the telly as you see them for a short time and never long enough to get to a stage of noticing the person more than their distinguishing mark.
Personally I do not like them, and I do not think I would have one. I won't say never, because who knows what life holds for any of us? I see people getting tattoos to cover up traumatic scars or amputations. Some have them to replace something important to them that has been taken away (nipples after mastectomy reconstructions, for example). Some have them to celebrate survival, or to remember a loved one living or dead.
Even if they are not something I would want, I can admire a carefully thought out and artistic tattoo. I just also can't help wondering what it will look like when it's faded and the skin it adorns has stretched or sagged.
In some industries they insist on no visible tattoos. In others they insist the tattoo should be of a size or a location that can be covered up. Eventually I think these rules will be substantially relaxed if the companies want any employees at all!
I do think some tattoos are going to render someone unemployable in some professions, but with people now able to work remotely where you only talk to them by phone or use email or instant messaging to interact with them professionally who is to know or care if they are covered from head to foot with tattoos?
