Original plaids had a long seam down the middle of their length, due to the fact that tartan came off the loom with a max. Two lengths of this cloth were thus seamed together to form the finished plaid. Material chosen should not be thick or blanket like, original tartan being a thin, tightly woven hard wool. Pure white cotton would not be seen, though the off-white cotton fabric called osnaburg is acceptable. Can be band collared, or with small falling collar.
Knee length is desirable.
Bone, horn, wood or pewter buttons. Large torries or pom-poms are a later development. Less common, but acceptable, are bonnets made up from a circle of woven cloth gathered and sewn into the headband. White Jacobite cockade of linen or silk in a bow or cross shape. Can be with the fur or hair still on.
