Ah, the Bush Cap, with tabbed flaps to be dropped to shield the back of the neck from the sun (never, ever saw/used that). The flap would be starched flat and then folded and ironed into a sharp crease at the top.
The purchased stiffener (emplaced, then the cap immersed in water) to give a stretched smooth look and slightly curved brill, followed by the ironing of the flap.
And the purchased aluminum small pack/ammo pouch frames to give a squared off, smart look to the fighting order on parade.
The old peace-time army with some in authority running amuck. 
True ... especially in Depot and so on, but some (maybe even many) RSMs and CSMs were far more interested in tactical/operational skills and knowledge and in working equipment and in seeing spit shone boots day-in and day-out. We still had spit shone boots, and we could square bash with any army, anywhere, any time, but we could also outdo almost any army, anywhere, any time at soldiering in the field. I can recall, very well, polishing - spit polishing - the (leather) soles of my boots (I did my junior NCO course with the Guards) and so on, I can also recall wiping the floor in an international patrol competition with the best that NATO could send our way.
And garrison dress was bush pants, shirt, high neck sweater in fall/winter/spring, bush cap (year 'round in some units) and jump smock (for those authorized) or parka shell when the weather required them. We managed to look smart and be comfortable at the same time ... despite having old kit.
