You changed your point. You said not a single plate was made for women but King of France famously made one for Jean of Arc.
Plate was Plate. There is just so much clothing and other armor that is put in before the plate even goes on that whatever bosom the lady has is completely covered.
Also plate isn't a yoga outfit, it has a lot of space in the torso area. Men and women can wear the same suit of armor and both have no difficulty to function.
Edit: also the link you provided also confirms what I said. Literally the first answer says men and women practically wore the same armor with little to no differentiation.
