I mostly dress weather appropriate. I think the sweaters, coats, and hats in this game are too cute not to wear right now. I do miss some of the summery dresses and flower crowns, but ehh...~winter is coming.

I do believe the villagers take notice, however. My brother thought he had his character wearing proper attire for the cold weather, and Dobie said that he must be cold with what he's wearing. My brother got annoyed by this and went back to his wardrobe to find something more "warm".This thread made me realize that your character doesn't shiver or sweat if you wear clothes that are inappropriate for the weather like in New Leaf.
