Full dress uniform is a special
uniform reserved for parade
or other ceremonial occasions. Prior to World War I
(1914-18) most armies of the world retained uniforms of this
type that were usually more colorful and elaborate than the
ordinary duty ("undress") or the increasingly drab active
service ("field") uniforms. The British and United States
armies were dependent upon voluntary recruiting and found
that a smart dress served to attract recruits and improve
morale amongst those already serving. The British regimental
system fostered numerous distinctions amongst different
units. Even the mainly conscript armies of continental
Europe retained many of the colourful features that had
evolved during the Nineteenth Century for reasons of
national and unit pride. Thus, in 1913 most French soldiers
wore red trousers and
kepis as part of their full
dress, the majority of British regiments retained scarlet
tunics for parade and off duty ("walking out"), the German
army was characterised by Prussian blue, the Russian by dark
green etc. There were usually exceptions to each of these
rules, often distinguishing elite units. Thus German
cuirassiers wore white full dress, British rifle regiments a
very dark green, French mountain troops large berets and
light blue trousers and so on. The US Army with its smart
but relatively sober "dress blues" was a exception, with
cavalry, artillery and infantry being distinguished only by
the different branch colors.
After World War I most full
dress uniforms disappeared. Many of the Imperial or Royal
regimes that had taken taken a particular pride in the
retention of colorful traditional uniforms had been
overthrown and their republican, fascist, or communist
successors had little incentive to retain old glories.
Elsewhere cost and disillusion with the "peacock" aspects of
old fashioned soldiering had a similar effect, except for
ceremonial guard units and such limited exceptions as
officers' evening or off duty uniforms.
