I want to thank you all for your replies. I will look into all of them.
About the neck join @Skell Dagger, I didn't even notice in the pictures that it isn't showing. There is a small amount of tattoo that runs onto the front of my neck. I can see it on me now, but what I didn't see until now is the HUD - Neck Tattoo, which I am about to add and click apply. Correct, my body hair is not part of the skin itself, nor from the Signature Gianni body hair pack, but it is BOM and advertised to work with Signature Gianni.
Ok, so I added the HUD - Neck Tattoo and clicked apply but nothing changed. In the meantime, I went to look at the tattoo again on MP and discovered there is a whole bunch of neck tattoo I'm missing. The only option in regards to the neck is applying it via the HUD. The body tattoo has the HUD apply system as well as a tattoo layer which when added makes the body tattoo look as advertised. So I am basically wearing 2 tattoos, being unaware of whether I needed to add both. The HUD applied tattoo is much lighter, and from what I'm seeing it's the HUD added "faded" tattoo is leaking through the added tattoo layer at the bottom of my hair and that is what we see in the picture. I am going to remove the HUD applied tattoo if I can and only use the layer tattoo to see if that resolves the problem. As far as the neck... I don't see a layer tattoo in my inventory for the neck tattoo. And like I said the HUD apply for the neck does nothing.
I really hope I don't have to use a Signature Head for this tattoo to look as intended. Which now that I look at it on MP, there is no Lelutka Icon associated with the tattoo so now I'm guessing that is my issue with the neck tattoo. There is an omega applier icon though, so I should go get the omega applier and add it through the omega applier, correct? I will be back with the above mentioned removal of the HUD applied body tat some time today.
Update: Removing that HUD applied tattoo has seemed to fix the hair problem going from one outfit to another. If someone can comment on the improper neck tattoo issue ( the lack of the advertised tattoo on the neck as well not realizing the product doesn't advertise Lelutka) and let me know if I should now pick up the omega applier. Will that apply the HUD only neck tattoo?
Again thank you all
