What kind of tie is Hilbert wearing?

I'm considering dressing as the mathematician David Hilbert for Halloween. I'm using as reference that one famous photo of him in the Panama hat that shows up every time someone talks about him. But I can't really tell what kind of tie/cravat/neckerchief he's wearing. What is that, and where can I find one?
