I must have been a bit vague. What I meant: I don't think the photo was taken while they were walking. They must be standing there like this since 1964. That was the time they had their final fitting on the trousers. More directly: The pants are to tight IMO. Maybe it's their way of playing with proportions, what do I know. I guess, Fuuma is needed to analyse the photo for us non-intellectuals.
