amusingly that armour design is probably more practical than most fantasy armour, although the skirts are a bit long for mud, the shoes are no good, the width of the skirts would snag on stuff when standing in formation but we can assume the petticoat is dress uniform.
My one major concern is the plates interfering with kneeling, but that wasn’t a universal tactic so I’ll give it a pass. also if you might still be able to and they’d sort of shield you while you did if you could manage so who knows.
edit: nerd points from my dearest, she highlights that the musket shown is of the correct style for the stand the woman is holding.
