I am picky about my jewelry. Mostly about necklaces though. I like them to lay right on my chest. If they are too short, I feel choked. I'm not sure if a necklace extender would help any. I've never used one before. Anyway, if they are too long, I'm always getting my hands caught when I answer the phone or something. Yes, I am a klutz. I'm not as picky with earrings. I just like them to look nice and not be too heavy. Necklaces though? A half inch could ruin everything.
