Swiss photographer Tiziana Vergari has gained quite the reputation on Instagram for her extraordinarily beautiful and unique pictures. With over 60,000 followers to her name, Vergari recently made a huge splash on social media thanks to a photo that really has people talking. Just last week, she uploaded what appears to be an optical illusion featuring an inexplicable amount of women. Her followers have been guessing, but nobody can seem to figure out just how many girls are in this photo.Is it one? Is it 2? Is it 3 or 4? Give us a hint, Ms. Vergari!
