Identify any specifically regional, cross-cultural or cross-national influences apparent in the styles shown in this portrait from the Northern Renaissance era.
The puffing of his "skirt," short breeches called "upper stocks," is a dominantly German influence. Human body form-altering puffing and padding is German and evident in the puffed skirt and cod-piece at the groin area showing through the space between the sides of the skirted jerkin (skirted vest). The black dyed wool of the jerkin is of Spanish influence as they developed the costly black dying process. The elaborate gold thread embroidery that decorates the jerkin and cape is of Italian influence. The "flat cap" or "pillbox" cap he wears, adorned with plume feather, probably from Africa, and jewels on the rolled up brim is associated with Henry VIII but is of French origin and is also called a French bonnet. The black opposing white (or near white) color scheme is Spanish in origin, though most often expressed as black embroidery on white silk or linen camica (men) or chemise (women) undergarments, which were unique in that they showed as sleeves, collar and shirt front (through slashed tunics and kirtles).
The King of France is wearing a French bonnet, a flat cap with a brim, here a wider brim than others, with jewels on the upturned brim. The horse's leather bridle and cover are cut-a-way from Italian influence. The heavy gold embroidery and black clothing (probably heavy wool and leather on the court boots) reflect Spanish influence. His hair reflects the shortened hair styles of Italian men, though they went even shorter. The puff padding showing at the knee is a German influence.
