People eventually figured it out.
The woman in the middle, outlined in blue, is leaning her torso to her left and her head to her right, so it's hard to tell which pair of legs is hers.
To make things more confusing, the two women on the left are both wearing black jeans. The woman second from the left has one leg completely hidden behind the other women's legs. If you look closely, you can see a sliver of her other leg poking out.
