For ceremonial armor it works. But for actual service boob armour like that is inpractical and sort of shot trap, where cold steel weapons can transfer the full energy of the blow/thrust. A singular bulge without dangerous corners is much better.
But since this fiction we are talking about the rule of cool/lewd trumps all.
It actually works for real life armor too, those fiddly bits actually don't do that. Shadiversity explains in what ways it works and doesn't work pretty well. Remember that the Winged Hussars had those ridiculous wings, which may or may not just be decorations.
