It seems as if her left leg ends with the right leg’s foot. Same goes for her right leg. At first I considered this yet another shameful Photoshop disaster, which I immediately forwarded to fellow webmaster who collects these. Yet, the twist came after I was explained there is actually nothing wrong with the photo itself! I couldn’t believe the photo was actually a “mere” optical illusion.
What has happened, is that Carme covered her left thigh in a way where it appears it’s pointing left, instead of it actually pointing up. This photo has been featured in several world sites as a wrong retouch, but after all the false spotlight it received, the agency who took the shoot explained how the legs were actually not crossed at all! I’m not sure I managed to explain what is happening here, but be sure to check the solution I created with help of the Photoshop (below) – it’s still hard to imagine, yet it should explain the illusion.
