The Internet is in chaos over colour of dress

The dress was posted on a Tumblr page by 21-year-old singer named Caitlin McNeill who lives on the tiny Scottish island of Colonsay.

"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 the f**k out," Caitlin McNeil writes alongside the photo.

In a telephone conversation with Business Insider , McNeill explained that the picture was a dress worn to her friends' wedding..

The dress was worn by the bride's mother and McNeill and her friends first realized there was something different about the dress when the mother sent her daughter the now-famous photo.

"What happened was two of my close friends were actually getting married and the mother of the bride took a photo of the dress to send to her daughter," McNeill explained.

"When my friend showed the dress to her fiancee, they disagreed on the color. All of our friends disagreed," McNeill said.

The bride then posted the picture on Facebook and her friends continued to debate the colour of the dress.

After seeing the Facebook thread, McNeill decided to share the picture on a fan page she has on Tumblr dedicated to a woman named Sarah Weichel. That's where the dress went viral.

Weichel is a talent manager who represents several YouTubers including Hannah Hart.

"The crazy thing is, I actually have nothing to do with the post. It's literally just a fan account of me, so my name and my photos are all over the account. I actually don't have anything to do with it. ... But I have been getting a ton of phone calls and emails tonight," Weichel said.

Kim Kardashian, Ariana Grande and Taylor Swift are some of the celebrities who have reacted to the dress.
