was it colder in the 20s?

I just watched The Changeling. I highly recommend it. Clint Eastwood sure has a knack for directing good, yet depressing, films. I must say it is quite refreshing to see a film that doesn't have to rely on sex to keep the plot moving.

I have one issue with the movie, which may not be a legitimate dispute. I'm not sure. Angelina Jolie's character wears heavy coats all throughout the film. The film is set in Los Angeles. In the spring and summer. I assume that it would be too warm to warrant a jacket that heavy, but then again, I've never been to California. I may have found the movie even more interesting had my focus not been repeatedly grabbed by what I consider to be an odd choice of wardrobe. I have two theories for the jacket/gloves combo:

1. Maybe the costumers were just trying to hide how painfully skinny she was.
2. Or it could be because the main character was met by such coldness in the cruel world of the 1920s.

But then again, I may be reading too much into it. That one sticking point aside, it was a very good movie.
