Is this dress white/gold or black/blue

[TheGrey]

Is this some sort of social experiment?

The item behind the dress (to the viewers left) is black & white - looks like it's in a milk cow pattern.

The black in the item behind the dress gives you a black baseline as the light brown wood trim to the right gives you a reference.

It appears to me to be a white dress/jacket with gold trim.

It's lit from behind, putting the front of the dress in shadow making the white of the dress appear darker.

I don't see anything black behind the dress- I see a light brown surface with a dappling of light and shadow.

This is very odd. My husband sees the black and blue hues as well.
