Have to disagree with your timeline. I used to watch Headbangers Ball back in the day so I really feel like I have a front row seat on this one. In 1985 not even most metal and hard rock bands had any tattoos. It’s almost strange to go back and watch some of those old videos now and see rockers NOT inked. However, by 1989, a lot of them had full sleeves, chest and back pieces. And almost all of them had at least several tats if not full arms and backs. I have to say this was the beginning of the modern tattoo era. Definitely influenced me. I got my first one in 1992. My last one in 1999. So yes, the 90s I feel was definitely the heyday. I feel you are correct that it has been in a slight decline ever since but I don’t think it’s going away anytime soon.
And I will admit, if I could just snap my fingers and make all of mine disappear, I probably would. But I can’t. No biggie. I really don’t care that much.
No doubt tattoos on men took off earlier. However, tattoos on women started much later, and my observance was that that didn’t happen until the end of the 90s. The full sleeve crap on women didn’t start showing up (on any women other than hardcore biker chicks and punk rockers) until the mid 2000s at the earliest.
