More work holiday party outfit help needed, please

I'm wearing this dress: www.amazon.com/gp/aw/d/B0084NXEXA/ref=aw_d_iv_apparel?is=l&qid=1354889386&sr=8-1&vs=1

with my standard black pumps:

How do I accessorize this?! The belt that came on the dress is black but not shiny... do I need to buy a shiny belt to match the patent leather pumps? Please help this fashion-challenged newbie.

The belt the dress came with will be fine.

I would accessorize with larger earrings and a few bangles, no necklace.

Thanks! I was afraid a necklace/belt combo might be too much.
