How was Joan of Arc's armor different?

Answer 1

As Female Knights were something new, portions of her armor had to be adapted for her feminine frame, and the breastplate was probably silk-lined on the inside to protect her breasts. it is also often depicted in the art of Joan of Arc that she had skirts that extended over her armored legs- and the coat of arms insignia displayed on the front panel , this was not worn in the field but in Church- as at the Coronation at Rheims and would be analogous to a modern Dress Uniform of the Army,. etc. there may have been a diagonal pattern on the skirt- and her crest enclosed within a Diamond lozenge-again indicating a Noblewoman- which she was.
