Myowyn - in english it's called a "pattern."
Here's a pattern for a justaucorp - note that it is the fuller version, rather than the narrower. You can adjust the fullness in the back by removing one (or two) of the gores in the back on pieces "A" and "C". If you're not familiar with pattern drafting (drawing your own patterns based on your measurements), you might want to start with something a little simpler than this, though. By all means, cut it out in cheap muslin first (always a good idea anyway) and consider investing in a tailor's dummy: example here (

Women did wear corsets (called stays until the mid-18th century), although they were different from the modern kind that nip in the waist and emphasize the breasts. The purpose of their corsets was to provide posture support - and flatten and lift . . . flatten the breasts and force them up because that's what fashion demanded (see pictures - 17th, 18th, 19th century). They were probably a lot more comfy than the 19th century version because they weren't as constricting around the waist. A good discussion of the development of corsets is

Handspun wool is much less likely to irritate than modern wool garments you buy in shops. Mass produced wool starts with treating the wool with a chemical that dissolves all the vegetable matter (seeds/grass/burrs/etc). It does a pretty good job, but it also alters the texture of the hair shaft. If you look at a strand of wool under magnification, you'll notice that it has overlapping "scales" - when the hair is spun into thread, those scales catch on each other and bind together. That's why wool cloth is so dense and sturdy, and why it can be felted (literally matted) into a solid mass. Normally, those scales will close (lie down) after they hair relaxes . . . the chemical that removes the vegetable matter makes them stay open all the time. And that makes the wool scratchy because its like each hair has teeny tiny teeth on it.
Some wool is naturally hard or harsh - usually that's used for rugs and stuff, not clothing. Some wool is as soft as silk (unless its chemically altered). Handspinners' do not use chemicals - I wash my wool with dish soap and remove the vegetable matter manually (yes, it is tedious and not perfect).
Some people who think they are allergic to wool because it makes them itch are really allergic to the chemicals used to treat it; or they are just reacting to the scratchiness of the treated wool. Some people are allergic to lanolin, the natural grease produced by sheep that remains on the wool even after it is washed.
If you really hate wool, find a handspinner and ask them if you can fondle something they have spun . . . you may be surprised at the difference.
His hairstyle? Not so much - really not for someone of his class. For working class folk, probably (though it might have been longer and worn in a queue). He should be wearing a peruke or periwig. I saw one picture of Sam Neill (in the trailer, I think) and he is wearing one, so they do realise that most men did.
