The South African Army used battledress as formal uniform (alongside nutria bush uniform) right up to 1994.
The original gaberdine was replaced by something more like barathea not long before I began my training. The woollie battledress tops worn by some of the older chaps in my regiment looked considerably warmer (an advantage, since we had our annual camps in the middle of winter).
I disliked the waist fit of the jacket (blouse, it was called formally) because it never quite lined up with the trousers (which we wore during our national service).
And when I joined the regiment and was issued with a kilt, I found that it often rode up above the kilt, too.
For that reason I personally would rather not wear anything that short with a kilt.
But you chaps seem pretty keen on the style.
Regards,
Mike
