Have you seen the 2005 version of The Lion, the Witch and the Wardrobe? While not strictly necessary, a familiarity with the costuming in that film will increase your enjoyment of today's Yarn Yuck offering.
That's because these bizarre collars are quite reminiscent of that crazy get-up worn by Jadis, the White Witch, in the movie's final battle scene. (This is the costume to which I refer.)
I'm right, aren't I?
This is the one she wears to fancy parties-- her version of the Little Black Dress:
. . . And this one is for when she's in the mood for something a little more colorful:
I suppose that if you're an evil witch ruling the world in a fantastical parallel universe, you can pretty much get away with wearing anything-- even this. I mean, if someone smirks-- stiffles a laugh-- raises an eyebrow-- ZAP! you just turn them to stone. (That'll quiet the rest of them!) But for those of us who live in the real world. . . maybe it's best to give this one a miss.
