I get what your saying, but lets please be realistic : if you have a situation where your life is on the line, will you custom order "female fit" kevlar vests, when you are an underfunded, overworked agency ANYWAYS?
not only this, but you gotta think of priorities : Any woman who has any brain cells would rather her tits be uncomfortably squished for a few hours, than have her guts blown out by a shotgun wielding cultist. Not to mention, I think the breast shaping idea might actually not be possible without fucking up the protective capability : please understand, kevlar ITSELF, just the vest, is 20 pounds : This drapping over you WOULD compress breast tissue by weight of the vest alone, and if something was made RIGID, to make it not compress the breasts, this would put a serious problem in the vests performance, and possibly even cause more injury if shot, due to the rigidity.
Keep in mind, the personal armor having breast contouring fibre makes sense, as its an alien material, but kevlar just doesn't work that way, as far as I know.
