What would look good with little black dress, black or sliver?

Well, both will match in terms of their colours.
But, since your dress is entirely black, I would say choose the silver.
This will work as your little pop in the outfit, and will definitely add some interest to the entire look.

I would say silver. Too much black is never good!

i would say silver cuz if you wear too much black you’ll look like you’re going to a funeral :X
haha have fun at your dance!
