Hello, I already use this skin: https://gardenofshadows.org.uk/gard...38044#msg638044
Sadly, it has a problem with the teen stage, where there is a line between the head/neck and the rest of the body and the body is of a different colour.

I have taken a look at the default database https://sims2defaults.dreamwidth.org/462698.html but from what I can see most skins there are grayish mannequin skins.

I would appreciate any default mannequin skins that look human, because I use mannequin skin as 'skin 0' now, with the help of the awesome mods that have been released recently.

Thank you for any advice in advance!

I took a look at the default skin you linked, and the TF skin is not matching the other skins nor the face-texture (hence the seam you mentioned) because it seems to be a completely different texture? It's much paler and colder than the other textures. I downloaded the original skin (Light Rose) and exported the correct texture, which I replaced the TF with in the default file. I'm not sure which skin the TF-texture is from in their default, but now the default is 100% light rose. I haven't tested it myself, but it's a simple default replacement so it should work as intended. Do let me know if it doesn't work or if the issue is still there

Oh wow, thank you so much, vegan_kaktus!
I only checked the teen skin in game, but that was the problematic one, so I think you fixed it! My teen sims look way better now
