One Reddit user explained that the “missing” pair actually belongs to the second girl from the left. Her legs are perfectly aligned behind the legs of the girl on the far left, making them almost impossible to distinguish. Their similar jeans and positioning create the illusion of fewer legs.

Another user, ElMangosto, broke it down further: Girl #1 has her legs crossed. Girl #2’s torn knee and white sock help identify her single visible leg, which blends with Girl #1’s. Girls #2 and #3 are leaning, adding to the confusion. Once you follow the clues, the illusion becomes clearer—though still a fun brain teaser. Share this with your friends and see if they can spot the “missing” legs!
