Goddam! Thank you!
That kind of explains the gold or black dress!

I can for the life of me only see it as white and gold, and I have really struggled trying to understand how others can see it as blue and black? I bet the picture you show here is a result of the research the picture of the dress initiated. It can't be a coincidence that the illusion you posted also is made with dresses.
