While the M1908 uniform was issued to most troops, some units continued to wear elements from the old uniform, especially the forage cap. Many infantry troops continued to wear the combined shoes and leggings made of pigskin (tsarvuli) hide material with leather straps. Could it have been as an insult to the Moslem Turks?

M1890 Infantry Uniform: In 1890 the Bulgarians adopted a uniform that was based on the Russian style of the era. The forage cap was the popular Russian civilian cap (furishika). The common wool (shaiak) of Bulgaria, an yellowish-earth-gray color, was used both natural and dyed in uniforms. Officially the color of the coat and pants was Dark green but much of the artwork shows Dark Brown clothing colors. Also, Bulgarian sources state that the basic regimental coat was actually undyed shaiak with Dark Blue pants, collar and cuffs. The color of the forage cap may vary but many sources (including the Bulgarian) has all caps as black with a cockade and facing color band. While even the elite Clementine Regiment is shown in the old style, most of the units still wearing this style would have been Reservists.
