up or down the cat goes

This picture is created that it can be seen either way. It is an illusion -visually- but it reflects the relative realty of life, certainly the relative perception of life. I saw the cat going down, but in the next fraction of the second I saw the cat going up. For me it is both way in the same time.

This picture was created in 1915 by the cartoonist W.E. Hill. Yeah, I married my young wife in 1974, but I knew it was a package deal, she came together with my mother in law. Like the cat, up and down, young and old in the same time.

But the dress, I don’t get it. It is blue and black.
