The Charles James Exhibit was great at the Chicago History Museum. Unfortunately you were not able to take pictures of the actual exhibit (I was bummed, because the dresses were A-Mazing), but here are a few pictures from the museum of other clothing making a part of Chicago's past.
Marshall Fields (sigh, I miss them, I don't really love Macy's)
Who know the Stock Exchange liked prints too :P
Typical beach wear in the 50s

If you are in the area and have a chance, be sure to check out the Chicago History Museum. I can't wait until they post the next fashion exhibit :)
