The Male wears a peaked red cap. He has a full beard, which becomes grey long before his hair does. He wears a blue smock with a Byronic collar or caftan neck (usually covered up by his beard). Then, brown-green pants with footwear consisting of felt boots or shoes of birch bark or wooden clogs depending on the area in which he lives in. Around his waist, he wears a leather belt with tool kit attached (contents usually = knife, hammer, drill, files…)
Facial colouring is fair, but with red apple cheeks, especially in old age. Then nose is straight or slightly upturned. The eyes are generally grey.
The Female wears gray or khaki clothing, also for the purpose of camouflage. Until she is married, she wears a green cap with her braids sticking out.
