The weird thing is, queri, that I've ignored all the rules, brought in characters with attached props (so I was too lazy to take out Nerd's eyes) and still had it work just fine. Admittedly, though, I think that messed up the head, but I didn't need it to fit the head, so I just went on. OK, let's see if I can mentally walk through what I did. First, do the clothes you use fit the characters when there are no morphs applied (it sounds like you're using the right clothes, but best to make sure)? I brought in my figure, didn't bother to set the MTs in Tailor because that'd be more or less just so I could see them, brought in the outfit -- Here we go, this might be a good check. Since the Tailor brings in the models without MTs visible, do the outfits fit in the window? If so, it should work. If not, Tailor can't help (yet. I personally am hoping maybe in future versions. ^_~) Also, my understanding is that Tailor doesn't create morphs that don't have a visible effect. When you dial all of the new morphs to 1 on the catsuit, does it still look like the neck and shoulders need morphs, or does the suit fit all right?
