The photo of the controversial frock (dubbed #TheDress on social media) went around the Internet Thursday night and Friday morning, polarizing viewers into two categories: those who saw it as white and gold and those who saw it as black and blue. It seems those in the former category have been tricked by the odd lighting of the photo (and maybe even by the physiology of their eyes) as the dressmaker has confirmed that it is royal blue with black lace stripes.
