Club Obi Wan

I notice Wested put new pics of the pants on their site. Now, is it me, or are the back pocket flaps way off? To illustrate: Compare the picture of Indy with his back/butt facing the camera in Marion's bar on the Indygear.com main page under the pants section to the pictures of Wested's pocket flaps. Clearly the flaps in the movie are much bigger and much more triangular than Wested's offering. I know gear-heads went nuts aiding Peter in making the shirt more screen accurate, but I don't recall the same enthusiasm when it came to the pants -- perhaps the reason for the not-so accurate present offering. Your thoughts.
Thanks.
