Sent to theatre 1944ish? As already mentioned they fought the Italians in East Africa, and also the Vichy French in Madagascar before they went to Burma.
I have a book with a couple of photos of the KAR in Abyssinia. One shows two anti-tank rifle-armed Askari in somewhat motley dress. Both have slouch hats and 37 pattern webbing. One is wearing a light coloured jersey and long trousers not tucked in.
The other is wearing the old-type smock (the sort worn in the Great War), long trousers and perhaps gaiters (hard to say, his anti-tank rifle is on the ground and obscuring his ankles a little).
Another picture shows a gun crew manning an ancient Great War era artillery piece. Again they are in a mix of smocks and jerseys, some with shorts and puttees, some with long trousers, some bare-headed and others with slouch hats.
The photos in the book of them in India and Burma are of a 'behind the lines' nature (on parade and such) and they have a much more smart and regimented appearance, being dressed no differently to any other British troops in that theatre (slouch hats again, brims not turned up at the side).
I have no pictures of what they looked like in Madagascar, unfortunately.
