I've often wondered why do various uniforms have those "poofs" on the outsides of the legs just above the knee? Was there a particular purpose to this, or a practical reason, or was it just the result of uniform designers saying "Hey, I kinda like poofs."
I think it has also been seen in other areas as well. For example, on the poster/cover for the 1970 movie Patton you can see a similar design, though much more pronounced it seems (though that could just be Hollywood exaggeration).
These are jodhpurs, a style of pants developed primarily for horseback riding. Their intent was to allow flexibility in the hip and thigh while the more narrow lower portion worked well with riding boots and didn't get caught up in stirrups.
Believe or not but this sort of pants were designed for cavalry in Poland by company Colmex in 1920. Just before Polish - Russian war in 1921. This company still exist in Poland but now is making ge pyjamas . Accidently, few years ago when taking about this topic with grand son ( J. Bonczar)of the creator on this company , he mention that buffing was done for three reason:
1) Mainly because that normal narrow trousers if inserted to high boots were restricting somehow wearer's movement.
2) Also if wearer chose to not insert normal pants into boots then his contact with the horse sides were not as good .
3) Solders like deep and large pockets which buffing allowed.
