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.
I agree that I don't want my townies too same-same all over the place, but I want each individual to have at least a cohesive outfit. The color tags are a good suggestion...limiting townie outfits to 2 colors would probably go a long way in helping them look at least a little more put together, even if the styles are clashing. A black and yellow rocker top with a black librarian skirt is going to look better than a black and yellow rocker top with a pastel orange librarian skirt, for instance.
