The fringe on the garment she wears in the “hat” sequence, which I had presumed was sable, is feathers, or rather down pelts, similar to the ones that made up the also rather visually appealing white coat she wore in the Dietrich in London special. I see no reason to doubt this assertion, after all, it’s not like they were suggesting there was no fur at all, or that everything in The Mad Miss Manton was fake. No, actually quite reasonable now that I look at it again.
I’ll blame my sable dreams on a combination of low resolution and highly wishful thinking.
Ah, but someone didn’t desecrate her grave because Marlene Dietrich wore a lot of goose down. Thus, finding photos of her wearing real fur is not exactly difficult. What is always enjoyable is finding those few that just knock you off your feet when you see them for the first time. This is one such example:
So the Shanghai Express collar wasn’t sable. I’m pretty dang sure this is fur, so I’ll get over it by picturing this one instead.
