I generally don't have much interest in formalwear with the kilt, since I never have any occasion to wear it. But I might have an opportunity to buy an older (1980s) green velvet Montrose at a very attractive price (less than 25% of what one would cost new) which would fit me perfectly. Just out of curiosity, what are the proper traditional options for wearing this? Specifically, is it only meant to be worn with a jabot and lace at the cuffs? I've looked on the net for images of people wearing it, and some people seem to just wear it over a white collared shirt with no neck adornment or lace, but I don't know if this is "correct" to do. Is a bowtie appropriate with it or not?

What levels of formality are appropriate for wearing a Montrose? And what should be worn with it to remain firmly in the traditional camp? It seems obvious that it's meant to be worn with a belt and waistplate, but what else that's specific to the jacket?

For reference, this is what I'm talking about:
