LOL. I don't know if what she's wearing is based on a real swimsuit or not (probably), but looking at it, it looks like it's supposed to have that slit there. It doesn't look torn, and it has the darker lines on both sides of the slit with it seeming like the darker lines are the stronger/frame points in the fabric. So, I suppose that it could have split really cleanly down the middle there, but still, the result looks intentional (though she obviously wouldn't be freaking out about that if it had had that hole when she put it on...).

Regardless, these are some excellent swimsuits that manage to cover everything and yet hide virtually nothing.
