The headdress was a wide-brimmed hat of khaki felt with a scarlet plume and lancer style lines.

After 1904 a number of new features were introduced, including a large drooping plume of black/green cocks feathers modelled on that of the Italian Bersaglieri.

Until the outbreak of the First World War, the uniform for full dress and off-duty wear remained khaki with scarlet braiding, piping and double trouser stripes.
