Blue dress and black jacket?

[lunicorn]

I've searched high and low for a warm shirt jacket to go with a Reiss blue velvet dress. The only thing I can find is this black fur jacket.

I think it's wrong because of the clash of colours. What do you think?

What about the dark grey one on the reiss page that they suggest goes with the (beautiful) dress?

Ignore me. I see it's actually navy (which would be fine) and out of stock. But maybe a dark charcoal grey?
