Ideas
I guess I'm just concerned that an attempt to fix all mismatching could result in the fashion equivalent to Sims 3 pudding face. I know that's exactly what some of you want, but I would rather my townies be individuals.
I would be open to a color coordination modification where each townie has a randomized color and their assets are filtered on that color, sort of like the color dress code from Get Together, but for an individual. But trying to impose pre-approved styles would make the townies too uniform, imo.
The fashion pudding face as you call it is no different than bisexuality being imposed on every single sim in the game. I think that is where the real problem stems from and why we see so many males running around with bows on their head and dangly earrings. and perhaps to some extent it influences some of the flashy, crazy clothing choices. I think gender preference needs to be more randomized and this would help create a more diverse npc crowd in the way that they dress.
