Well, this is actual the original game mesh that should popup.
But like most skinners(especially skintone) you prolly once have installed windkeepers or guinyr's files.
Windkeepers replacement file relinked the original boxermesh to the hidden fullbodynude so you guy's would have a nude shape to make your skintones on.
She also made a ''invisible undie'' file that came with it to delete the boxertextures.
The installation of my files reverts everything back to the original game meshes but updated with sexy feet.
So wat you see is actual the original mesh that came with Maxis except that there's still the invisile undie file active.
Jw had the same prob, not only with this one, also the Elders Teens and female i think.
Its up to you wat you want, keep it as it was, then you have to remove my file for the Adults and download the individual files for them, you can also use Warlokk's XHI Replacement then if you like.
You just have to delete the undiemeshes if im correct.
Go here if you want to combine the files, something i dont recommend

but we get it sorted out if you like:
SeXy Feet*Default Replacements*Male/Female seperatesOr you switch back to the original game files and use the meshes/outfits we made for skinners:
You will find wat you need at the adult site in JW's section ''Things''
Its called: ''Nude Clothing for Sexy Feet''
