Last week, Swiss photographer Tiziana Vergari uploaded this photo of girls sitting in a room in Conthey, Switzerland, as part of an Instagram hashtag project.
The project, labeled #WHPidentity, encourages users to submit photos that showcase individuality.
Many people took to the comments to show an appreciation of the picture, but a common question kept coming up. How many girls are actually in the photo?
The answers have varied.
And amid the confusion, the question still stands.
BuzzFeed has reached out to Vergari for comment.
