A year to the day after The Dress took over the internet, a new confusing piece of clothing has appeared.
An image of this Adidas jacket was posted on Tumblr and Twitter this week, and it's already started dividing opinion.
Is it blue and white? Black and brown? Maybe even green and gold?
Everyone seems to see it differently, and some fairly passionate debates have sprung up on Tumblr.
After last year's furore over The Dress, scientists studying the responses found that the brains of those who saw it as white and gold were working extra hard.
It's not clear whether the same amount of research will be devoted to The Jacket.
