I've always loved the dresses worn by soldiers of the 17th century, although they didn't actually wear uniforms until the second half of the century. In addition, the new clothes that the soldiers received when they joined the army needed just a few months of campaigning to be reduced to some dirty rags. But I find strangely attractive even the ragged soldiers or those who had nothing to cover their nakedness (if you consult Spanish documents of the period you'll find many times this expression).
It's not blatantly elegant, this gentleman?
Also fascinate me, for some time, the Roman soldiers from the third century, 100 years focused on the so called "Crisis of the Third Century": civil wars, military anarchy, economic collapse, epidemics, barbarian invasions... The whole panoply of all the troops of the Roman Army experienced a curious evolution, largely due to the high costs involved the manufacture and maintenance of armor the previous period's commonly associated with the Romans.
The costumes and armor of these Lanciarii of the Legio II Parthica are at least curious.
