In a game series with hundreds of characters, some similar outfits are bound to emerge. So while I don’t know, and while it’s probably impossible to know just how much of a coincidence it is, I saw that Olwen and Limstella, the latter one of my favorite FE character designs, have pretty similar outfits.
(Olwen was made for a game released around five years earlier, and there was some high-profile turnover in IntSys between them, for what it’s worth).
