[Help] Any way to disable Hot and Cold outfits? *Answered*

I don't think the option to ignore temperature effects ignores rains (might be wrong though, never tried it). Even if it doesn't, for only 500 aspiration points you can get them a trait (Waterproof) that will ignore the rain. Just cheat the 500 points if you want to get it on all your sims without having to work on the actual points.
