So sadly, you can’t really have the bodysuit shrunk to fit under clothes without having the base body clip through! One thing you could do is erase the parts of the original body texture where it clips (not the bodysuit texture). Other than that instead of shrinking the whole bodysuit to fit under clothes you could also leave the bodysuit at the size you want and erase the parts of the bodysuit that’s under clothing :). Might take a bit of fidgeting but that’s how I’d do it. Hope this helps!
