It's happening again, so brace yourselves. The so-called 'great dress debate of 2015' is back with a vengeance (and a pair of flip-flops).
This time around, the pic appeared on a Portugese Twitter account, asking users what color they saw.
The situation instantly reminded netizens of 'the dress', which became a viral phenomenon in February 2015, leading to endless debates, memes, hashtags and even a few articles in peer-reviewed science journals, looking at why some saw the dress as white and gold, and others as blue and black.
So let's settle #FlipFlopGate: what do YOU see?
