This is at the Van Gogh Portraits exhibition at The Courtauld Gallery in London. We went there a couple of days ago, and could not help but notice the attire of some of the gallery visitors.
The woman in the gathered tulip dress (as Tamara named it) stood out, but then there was the man in the long overcoat in mauve and purple checks. Pretty natty, eh.
And to anchor the photograph in time, there is man wearing a mask.
