>>17756692 (OP)The fashion of the Landsknechte is a case of showing off the personal wealth of the individual in a profession that otherwise allowed for few luxeries and that few survived.
The colorful and bright cloths, the puffed sleeves and hose (which were more difficult to make than simpler cuts and consumed more fabric) all demonstrated that the respective soldier was able to spend much money on his clothing.
This became possible by a decree of Emperor Maximilian I. in 1503, which exempted the Landsknechte from the sumptuary laws that would normally apply to the people of lesser social standing - like soldiers.
