I'm still being all obsessed with True Blood, so it's not surprising that I noticed the jewelry some of the characters are wearing, I guess:
This is from Season 1, the first time we see the vampire bar Fangtasia. In the book, it's explained that these vampire bars are wildly successful because they cater to tourists and "fangbangers" (basically, vampire groupies) and so to make it work, the local vampires have to spend a certain amount of time a week sitting around in the bar looking all broody and vampire-ish, playing on human expectations of how vampires look and act. So it makes a good bit of sense that this necklace and earring set, while cute, looks like it's something that came from Macy's or somewhere. (Hot Topic, maybe.) Actually I swear I've seen it before.
(In the same scenes, the human heroine Sookie wears a red-and-white sundress and a really cute pair of tiny red dangly earrings. So she's color-coordinated but sort of anti-goth.)
