Viral photo: How many girls do you see in this image?

A photo on Instagram is inspiring debates reminiscent of the one started by the white-gold/black-blue dress photo from 2015. This new photo is going viral after people on the internet disagreed over how many girls were there in the image.

Swiss photographer Tiziana Vergari put up a photo on her Instagram account one week ago as part of her art project. Since then, the photo has garnered almost 15,000 likes and over 1500 comments. While most people think that the photo is of two girls, others argue that there are three or four.

This new debate comes just a year after The Dress went viral in February 2015 because people weren't sure what colour it was.

So, how many girls do you see in this photo?
