Layering jewellery

I've been going thorugh a phase where I seem to want to layer my jewellery. Rings, bracelets, necklaces: you name it, I'll layer it. It makes me aware that I really don't have enough jewellery (my three jewellery boxes tell me a different story). I can't afford a leather jacket, so maybe more jewellery would be a good way to punk it up?
