Hi ^^

I hope there's a simple solution to this, but so far I can't find it.
I'm trying to replace the toddler badger outfits (the hairy pajamas that came with OFB), but all of the skin below the neck is black, like this:

I think it is the alpha texture file, because the original outfit covers the whole body and therefore it is fully white. But how do I replace the old alpha texture with the new one in SimPE? I really cannot find it and I hope someone can give me advise on where I should look
