S and B experts please help! interesting black/White necklace for Wedding Guest Outfit!

[polyhymnia]

Off to a wedding Saturday week and going to wear cotton dress with lovely black and white 'retro ' landscape print.

Accessories mostly sorted but I really need to complete with a gorgeous necklace to sit in my V neck ( have ample bosom!).

Can be black and/or white. Nothing itsy bitsy/pretty pretty/ minimalist so can be be bold/quirky but mustn't fight with the print.

Must be at least 18.5-19 inches long.

Not hundreds of ££ but not cheapo-looking either .

A tall order I know but am hoping you S and B experts well up to it!

Have a look at my friend's necklaces here

Thanks really like some of those. Think the one called Brighton might fit the bill.
Have you seen it in RL ? Slightly hard to imagine what the 'rubber' bits look like.

Are you in London? I'm sure she'd be able to show you some IRL...

Yes but in Rome at moment and not back till a week today - but might still be able to get there.
