Do you remember 'The Dress' from 2016 that broke the internet? Twitter was divide back then with many arguing about whether the outfit is black and blue or gold and white. Well, a optical illusion debate is back but with a twist. This time it's about a woman's neck. 

Twitter user Marty Mula shared the picture last week saying he thought “this was her neck”. Turns out, she wasn’t the only one. Several people have been left confused about what they see in the picture - making it go completely viral. Since being tweeted, the picture has collected over 32,000 retweets and more than 70,000 ‘likes’ – and still counting.

The image shows a frizzy, long wave of hair covering a girl's bare back; or it could be the back of the neck of someone with an unfortunately brief haircut. For further perplexity, check out the picture below.

Thought it was some girl with short ass her that suffered from heat damage and has a long ass neck. But instead it’s a girl with long hair and has a perfectly shaped back
