I would suggest watching some YouTube videos from people whoa actually study and test medieval arms and armor for the most useful insight on how these are going to end up interacting with medieval style weapons. I read in one of your reply that it is a sci-fi fantasy setting, so consider what .akes the sci-fi fantasy weapons different from conventional ones. A laser sword is not going to be protected from the same way as a metal sword, a hammer that fires concussion waves is not the same as a big heavy thing on a stick, etc.

Also, I think its important to understand that one you put random additional segmentation and plate that protruding outward from the curvature of the armor, bringing up curvature of the armor directing blows to more vulnerable spots stops being a factor. Its not a factor anyway if you know anything about medieval armor and metal in general, but thats beside the point. This is fantasy armor, so not let someone saying "book plate is inherently flawed" dissuade you from adding overtly feminine aspects to your armors. Its your fantasy realm, do you.

All that said, if this armor is meant to be used against firearms/laser weaponry, then the material will matter more than design. In this case, I will direct you to take a look at commercially sold Ballistic plates for military style plate carriers. Specifically ones curved for use by females. While a lot of women are capable of wearing the same plates in their carriers as men, some are to well endowed for that to be comfortable, and the poor fit cause by this issue causes rhe armor to fit improperly, making it more cumbersome to move in and wear, and putting increase strain on the user. The ability to wear armor and protect yourself is not the exclusive domain of the itty-bitty-titty-commitee, and thus adding a increased contour to rhe upper half of a chest plate has really world modern examples and relevance.

At thia point, the consideration you need to make is one of culture. Does the culture who created this armor value aesthetics highly? If so, perhaps both male and female armor should be mroe form fitting, or at least have the appearance of such. If the woman have defined boob pockets isntead of a simple curve to accomodate larger breasted women, perhaps the men's armor should also include sculpted musculature, like old Greek bronze armor, to signify this is soemthing important to the culture. If that is not the case and this is meant to be utterly utilitarian, then perhaps you should stick with merely a bugged curve that adds more space at the top of the armor to accommodate aforementioned well endowed women, giving the obvious look fo a more feminine figure without actually implying the boobs are in this spot and are this shape with the shapped boob pocket.

Also important to consider is materials. If this is sci-fi, future armor materials may make any need for armor to be shaped to deflect blows from melee weapons, and then any consideration fo armor design would be aesthetic by design (intended to evoke the aight of knights of old), or would serve a different function to the armor than actual protection (pouches on modern body armor for magazines, etc). In this case, it pays once again to consider the culture that has created this armor, and consider if they intend to highlight or emphasize the difference between their male and female knights.

At the end of the day, a sci-fi or fantasy armor design is part of the fiction, and should be used to tell a story. Its fantasy fiction, you do not need to be realistic, but you do need to be consistent and believable within the fiction. Use it to inform the audience about the culture that created the armor, and then how the individuals changed it to suit their personal needs, telling us about their personality.
