Pastels for Fall: Baby Blue Leather Jacket

Who was it that decided pastels were a Spring/Summer thing? Was it the same narrow minded thinker who said "No white after labor day"? I'm pretty sure "Winter White" has put that old trope to bed.  So why not embrace pastels for fall? Baby blue looks crisp and downright wintery when paired with suede booties and a fuzzy turtleneck. Fashion rules are made to be broken, right?
