I have a rifleman frock aka hunting shirt or frock with an orange cape. I have seen hunter orange waistcoats that guys have had custom made or made themselves. (Johnson Woolen Mills recently had hunter orange wool back in stock for such projects, but it's pricey)
I did see one of the makers of higher end period hats that has a solid hunter orange felt round top broad brimmed hat, can't remember who.
One of the tough things with this is that unless you spend the money for the wool material. Natural, period correct hunter orange fabric is surprisingly hard to come by.
I don't generally love a caped hunting shirt,
I find the cape to be a nuisance.
So, when I had an opportunity to buy a few yards of hunter orange wool fabric, before Johnson got theirs back in stock, at a reasonable price, I bought some.
I went with a far more versatile option.
Period correct for most of the periods we cover here. Our muzzleloader season is in December, so cold and wet are always options during the season here in New England. This keeps me, and my gear, warm and dry.
A nice simple matchcoat.
Just so you know, there are those who vehemently disagree with spending time and money on "period correct" hunter orange clothing.
