Yeah, it looks odd, right?  
But apparently that's how you're meant to wear it.
Bit hard to describe but the back piece rises up and straps attach at the top of this piece. You can't really cross at the back. You could go straight but the straps are way too long, seems like they really did want front crossing for this model. Incredibly confusing to put on.

That's also why my wife didn't really start using it, she tried it on, basically said "that's just dumb" and it has remained in the closet ever since.
