In a lot of games you can see female characters wearing armor that is clearly designed to fit and visibly accentuate the shape of their breasts. The reason for doing this from a design standpoint is absolutely clear – ladies always have to look sexy, no matter how much armor they wear.
However, you will never see anything like that in real life. Female vests with breast pockets simply don’t exist . This is not a matter of aesthetics, but of practicality. Modern bulletproof vests would be way less effective if there were any cavities in their metal plates. It’s simple physics – deformed metal is less durable.
In the Middle Ages, women-warriors ordered custom-made armor to fit their body shape, but those were extremely rare cases. On top of that, the armor was usually so heavy that women simply couldn’t wear it. Even men had to bring assistants along who would help them get up from the ground, if they happened to fall down.
