Honestly, I wish that they'd had indoor and outdoor categories for the cold weather outfits or just treated the cold weather clothes like the outerwear category in previous games. Having one cold weather outfit for outerwear and one for inside in your normal alternate outfit set-up isn't good enough, because when a sim has two outfits in a category and they automatically change their clothes to that category, they always pick an outfit at random. Call me obsessive, but I like my sims to wear their warm coats outside and their toasty sweaters inside, not the other way around, and fixing the game's mistake manually really takes me out of my play session.
