Fiora is one of the biggest egos in the league - why would she wear such a bland outfit?
Okay, so I see where Riot was going here, as her now clothes pretty much resemble the classical duelist/fancing attire. And i guess it makes sense when you reduce Fiora's identity to "being a duelist". But isn't the main point of her character, that is emphasized both in her lore and in her voice acting, how prideful and arrogant she is? Her ego is so big it might only be second to Draven. And yet Riot decided to switch out her adorned armor for a comparatively bland duelist attire.

I mean really, Fiora strikes me as the kind of person that wants to look "glorious" and would reject wearing a boring white one-piece with black pants. She would turn up even to a duel in the silver boots and the shining armor with the gold adornments, no matter if it hinders her movements. And I think that's what makes her fun and interesting as a character. Unfortunately, her new clothes reallly take away from that part of her identity.
