If nothing else, brainer, "male" body types for "female" heads is a sure fire way to avoid boobplate.
If you imagine your character flat chested, tall and stocky, the "splint plate +2" male model is just better. I might do this myself without creating a trans character if a muscular build for women doesn't really exist. I will be skipping potential sex scenes, anyways. Whatever other impact it may have, is nonexistent for me.
Of course... it should also be possible to download a mod with a custom build. Enjoy the one singular armour that doesn't glitch out on it. Probably has colour variety. Also a good option, since +2 armour will never /need/ changing.
