I noticed that too. I had two sims at a bar that fit the description (minus the clothing because of them wearing their summer wear) and the suspect started acting nervously and I knew then it was her. I also delete all the generated sims from my game so I know who's who. So when I see a new face they're usually the suspect lol.
I wouldn't see this as breaking necessarily as a sim should be in the proper outerwear depending on if it's too hot or too cold. It just makes finding the suspect a little bit more challenging which is a good thing if you ask me lol.
ETA: However when they are indoors I do expect sims to be back in their everyday wear which the game is having trouble with right now. So if let's say I have to find a suspect in a bar and they're still wearing their hot wear indoors that seems odd. They should have changed back into their everyday wear. Only accepetable to see the suspect in hot or cold outfits when the suspect is outside.
Also I did not know about the ask about outfit option @LadyKyn thanks for the tip. I will use it in my game next time I play.
