Mostly necklaces and earrings, which can complement glamours really nicely if you pick the right ones. There are also some nice bracelets but the can be hard to work with around sleeves.
My Viera tends to use the flower earrings in coordinating colours with his outfit. It lets me add an extra splash of colour higher up on the outfit.
For examples with my Viera:
They're not a structurally huge part of the outfit, which it why I mentioned them only as an aside, but I still think it can make a difference to the outfit if you find the right ones that look good with it. Even the simple hoop earrings from ARR come in a few striking colour versions – the red Manderville earrings are great, and there's a cyan blue version that can look good paired with techy gear that has the same glow.
