Back in ‘52, when the old salts got tired of us boots bitching about not being allowed to wear Levis, shirts w/o collars (no t-shirts) etc. they would tell us how—in the OLLLD Corps—at Quantico, for instance, Marines had to wear a coat and tie just to go to the base flik.
Usually, off base uniform was winter greens/summer khaki w/field scarf (no short-sleeve shirts in those days), w/barracks cap—sewed-up c-caps were out—had to show liberty cards to MPs going ashore at maingate and/or on the liberty bus. Dungarees off the base was unthinkable.
I was in mid to late 60s and while the rules and regs weren’t quite as strict as “Old Corps” days, they were damn close. Semper Fi ...
Navy in the early 60’s was dress blues/whites off base, no undress or dungarees.
