t's the debate of the year so far - well - on Twitter at least and has been the top trending topic worldwide.
It's all about #TheDress and whether it's blue and black (#blueandblack) or white and GOLD(#whiteandgold).
The whole debate started when Scottish singer Caitlin McNeill posted a picture of a dress on her Tumblr blog.
She asked her followers: "Guys please help me - is this dress white and GOLD, or blue and black? Me and my friends can't agree and we are freaking... out."
Taylor Swift says it's obviously Black and Blue
Kanye, Bieber and Demi also see Black and Blue
Kim and Julianne Moore see White and Gold
What do you see ?
