How about this for a wedding?

[gja1000]

I'm not very good at projecting what something will look like (accessories) - I pretty much have to try it on and see how it looks. I'm good with judging how good it looks when I see it, but projecting - not so much

That said, I would try a chunky red necklace to see how it looks.

I would probably end up with sparkly sterling silver - maybe even some cubic zirconia for sparkle.

The right black necklace would also look good, but since your shoes are black, I'd probably go with red or silver for accessories.
