Help with some jewellery please.

[Megatron]

Anyone have any ideas about what jewellery to wear with a very plain black evening dress? I think something silver and fairly chunky would be best but not too sure so any suggestions would be great.

Anyone? I'm desperate!

oooh you could wear ANYTHING with that! What's your style generally?

I'm very casual (jeans and converse etc) but I need to make an effort for this event and I want something that will look really good and not cost me a fortune. I like a lot of Alex Monroe jewellery but I think I need something chunkier as the dress is so plain. (and cheaper!)

Some ideas
Beaded collars are trendy at the moment:

Or maybe something "classic":

I've been seeing a lot of chunky, colourful plastic (but stylish) necklaces lately-
Zara has some nice ones

what's your budget?

This?

Have been looking at this whatdoyouthink? which is similar Aquelven. I didn't really want to pay more than about £20 if I can help it but I can't see much I like.
