You asked about “armour for women”, but I’m afraid that’s not exactly the question I’m going to answer. I’m primarily going to cover the physical issues of armour for people of all genders with typically female bodies in this post. I will also discuss a few social/cultural issues around gender and armour, particularly relevant to women of all body types, at the end.
You may also find bits of this post useful if you have a body with some but not all typically female characteristics, like wide hips or breast tissue or low testosterone.
N.B. Throughout this post I am going to say “chainmail” when I refer to armour made out of lots of little rings joined together, because I gain sustenance from the tears of angry pedants.
