In the "something else" category: I have a black woven cord bracelet that I wear every day, that doesn't strictly qualify as jewelry but I feel lost without it.

Also, I cannot wear necklaces. Plastic, beads, pearls, metal, whatever: the only time I can stand to have something around my neck is if it's made of leather, and even then I can't wear it for very long. Necklaces itch, and I keep scratching at them and eventually end up with red patches all over my neck. I think maybe I was hanged in a former life. Or possibly decapitated.
