I read a study from New South Wales University
"Analyses revealed a significant linear trend, R2 = .18, F [1, 58 ] = 13.04, p = .001, such that more coordination was linked to more fashionableness, consistent with the general importance of matching. Importantly, however, this linear trend was qualified by the predicted quadratic effect, R2 = .44, F [2, 57]= 22.23, p<.001, such that peak fashionableness was achieved by moderately coordinated combinations. This quadratic effect accounted for twice as much variance as the linear effect."
(more coordination was linked to more attractiveness
+ people like things to match)
