A FIERCE debate is raging in The Bolton News office and across the internet - and it's all about the colour of a dress.

Half of our staff think this dress is blue and black while the other half think it's white and gold.

As you read this, people are shouting at each other and accusing each other of playing a prank.

Yes, we have nothing better to do.

Anyway, we're not alone. The internet has gone mad over this dress and #TheDress is trending worldwide on Twitter.

The picture of the dress was first posted by 21-year-old Caitlin McNeill after noticing her friends saw different colours in the photograph.

She said: “I swear to you its no hoax. I saw the dress in real life, it’s blue and black. Some people just see this pic as white and gold. I DONT HAVE ANY ANSWERS BUT I NEED THEM."

Celebrities including Justin Bieber, Taylor Swift and Kanye West have weighed in on the debate.
