Interpretation of the picture
The picture on the previous page shows that braies are large voluminous trousers that reached to mid-calf length. Whenever they are depicted they are always shown as white. (This is also the case for woman's headwear, male coifs and undertunics. The Maciejowski's use of colour seems to reflect real life, albeit one with a slightly limited palette). The braies hang and crease as if they were made of fine linen.
A slit on the inside of the leg allows one end of the leg cloth to be tied up to a drawstring at the waist near the front, and this strip of cloth lies against the side of the leg.
The waist band has a great deal of cloth bunched up in it, and this cloth produces the unflattering "saggy-backside" appearance of the braies. Under normal outer garments - when the braies are presumably still worn - this waist band is obscured by the cloth gathered at the waist of a belted cotte, while the slit in the legs of the braies allows the cloth of the legs to be smoothly overlapped underneath tight woollen hose. When worn with hose, the hose ties are then attached to the same point on the front of the waist band drawstring.
