It's not the dress, but it's another online photo causing the same kind of debate.
In an Instagram photo uploaded by 43-year-old Swiss photographer Tiziana Vergari last week, the artist captured an image of two girls — or four or eight or another number altogether — with the tagline, "Same but different."
"[I] absolutely did not expect this photo to go this viral," she told The Huffington Post Canada.
So how many girls are in this picture?
Internet users have said everything from two (the second girl is looking at her own reflection) to four (the second girl is looking at another girl).
Vergari revealed the answer on Instagram, noting the girls in the picture are her daughters.
In February, another picture of a woman with her two daughters went viral, after each person in the picture looked eerily similar.
Vergari's photo was featured on Instagram's official account, after the company asked users to submit photos with the hashtag #WHPidentity to celebrate individuality.
