#gradually packing on the pounds with each suit of armour in that last pic

Twin Moon Knight Rellana has the best rendition of "boob-armour" I've seen in fiction:

Edit: Why'd Tumblr mark this as mature??

Why The Trope Is Usually Dumb and Bad:

In general, an effective suit of armour needs padding underneath to absorb blows, meaning it shouldn't fit so tightly around the chest as to require a built-in bra, and the common boob-armour divot used to define cleavage only serves to direct attacks directly into the chest. It's impractical to both make and wear. That COULD be used by a smart writer to say something about the character wearing it, but almost always it's just fan-service at the cost of the story's cohesion, with no deeper meaning.

Now let's look at Rellana's armour:

Why Rellana's Armour is Cool and Good:

Rellana's armour was carefully designed to avoid all the common pitfalls. First and foremost, there's no cleavage! Instead, they've taken a cinched-waist breastplate that normally utilizes an hourglass shape (example below), and added subtle definitions that get the point across without sacrificing protective capabilities. Sure, it's still more form-fitting than real armour, but that's standard for From Software's stylized armour designs.

Next, the armour directly aligns with the character and setting it's found in/on. Rellana isn't some standard soldier; she's ex-royalty, which opens up a rarely-accessed avenue of historical precedent. The ceremonial armour of nobility was RIFE with impractical designs made only to show off. Enormous codpieces, crazy skirts, breastplates with sculpted pecs and abs, etc. (also see below)

Now, it's still impractical to FIGHT in ceremonial armour, but Carian Nobility (and ER as a whole) already has a well-established tendency of doing so. Plus, it aligns directly with what we know of Rellana's character: she's a wizard-princess turned warrior that really wants to catch the attention/affection of Messmer. Thus she wears armour that declares her as Knight, Noble, and Woman.
