Happy Halloween from the Jeanette MacDonald Blog!
I KNOW I've seen a photo somewhere of Jeanette and Gene in costume for a party of some sort, and I would gladly post if only I could find it... and of course, I can't. But I know it exists. I'm also pretty sure Kayla once told me that Jeanette used one of Norma Shearer's costumes from Marie Antoinette for Halloween once. That trumps basically any costume I could ever come up with.
Have a safe and happy Halloween!
