On Josh Sawyer's BG3 stream, he mentioned that when working on Neverwinter Nights 2, Wizard of the Coast had very strict guidelines as to how the aesthetics of the armor and clothing needed to be. Essentially, they had to follow the D&D 3.5e armor design guidelines, etc.

I wouldn't be surprised if it's the same for Larian. Which means expect lots of big pauldrons on heavy armor (see Paladin with plate from the 5e Handbook).
