Not if animations have to be tweaked to accompany the right pronouns, which is otherwise irrelevant to this thread, it was just an example of something that wouldn't be in for the same reason fat bodies wouldn't be in. Also, we probably wouldn't have any fat bodies on NPCs if the clothes didn't also work on them, because with all the rewrites and character testing/debugging Larian has done, I doubt they'd leave in characters that would glitch out the game if the suits didn't work right.
NPCs don't have to deal with the player changing their equipment every time it strikes their fancy, nor do their character models have to work with every single possible animation that every character class action might require, and the only quality assurance that needs to be done on their animation work is the stuff directly related to the few specific things the developers want them to interact with.
