This Shoe Will Ruin Friendships Like 'The Dress' Did

We're not saying anyone's wrong. But really, it's the left one.

A new optical illusion is confounding the Internet, just like "The Dress" did only months ago.

Twitter user @totallymendes posted the following image on Wednesday.

Social media users have since divided themselves over which of the nail polishes matches the shoe. It had been re-tweeted over 5,000 times as of Thursday afternoon.

"I'm going to bed because it's 1:25 a.m. but I wonder how many RTs this will have when I wake up," @totallymendes wrote.

The picture, which is trending under the hashtag #TheShoe, comes five months after "The Dress" divided people between those who thought it was black and blue, and those who said it was white and gold.

Scottish musician Caitlin McNeill, who posted the original picture of the dress to her Tumblr account, later confirmed it was actually black and blue.

#TheShoe is causing similar anguish only one day into its life.

And at least two brands have already capitalized on its popularity.
