Wow, I never expected EAxis to mess up the fat morphs so much. I think the worst case were the male fat morph waiter outfits, the clothing literally explodes.

For the waiter outfit at least, you'd never mormally see it in-game on a fat sim without mods or cheats. Not sure about the ninja, is that one in the catalog? So Maxis was probably just saving costs and time by not fixing it.

Yeah, the ninja one is part of the OFB mascot outfit collection, so it is in the catalog.
I had opened CAS in debug mode just to take a look at the outfits and got jumpscared by that waiter outfit. EAxis weren't really expecting modders to be able to create a mod which enables fat townies/service Sims, so that wasn't a big deal back then. But if you make a waiter playable either if your Sim marries one either with cheats, and you keep the outfit that they wear, and then the waiter becomes fat... Disaster.

@jawusa made a fix for the waiter:

I do know about the fix, but unsuspecting simmers that have the townie fitness diversity mod or in this case would definitely be frightened from that mesh flying around the place!
