Removed tattoos reappear under certain circumstances

I did a little experimenting and I found out you can delete individual tattoos, it's just a little complicated. If you have had a tattoo on your Sim while you've been looking at multiple outfits, to delete it you can go to each outfit you've had open and delete the tattoo in each. If you can remember which outfits you've had open, but if you can't just go through all the outfits and delete the tattoo in each, if they have it. If you switch to any outfit without deleting the tattoo from the previous outfit, the tattoo will propagate to the new outfit. Sorry if that sounds a little like I'm repeating myself a little, I just thought I'd try to be as explicit as possible. Again, deleting all tattoos does definitely work if you're okay with starting from scratch.
It seems to me like (and I'm not necessarily knowledgeable here), with the new tattoo system, that when you switch to an outfit, new tattoos are copied to the outfit but the absence of a tattoo isn't, and that's I think what's changed with the new system. Hopefully either the workaround or the more detailed description is helpful.
