What can I wear with this dress?

[WhenIGrowUpIWantToBeAPenguin]

I have a black tie do to go to this week and am wearing this dress. I have blue shoes, blue and gold jewellery and probably a gold clutch - but am completely stumped as to what I can wear as a cover-up...

I have a beige pashmina but it's a bit dull. Can any of you lovely lot suggest something alternative? Budget probably up to £50 but will stretch for the perfect thing, especially if it's versatile and I can wear to future events. All suggestions welcomed!

Maybe a gold version though if that's your metallic. Will keep looking!
