Based on what I have learned so far, it is my understanding that the Highland regiments wore the khaki Tam O' Shanter in the field (with officers perhaps wearing khaki balmorals instead). The diced glengarries were allowed to be worn for walking out and more formal occasions. But what about the diced balmorals (sometimes referred to as Kilmarnock bonnets)? I could find no mention of the diced balmorals in "Dressed to Kill". I have seen examples of the diced balmorals, but have never seen a WW2 era picture of a soldier wearing one. When would these have been worn? By whom?
