That kind of reminds me: I hate it when there's no way to make ridiculous-looking armor look like the character's default or canonical outfit.
You know what I mean; it's like when you dress up as some sort of pimp-wizard-clown-Batman because you need that +2 to critical hit, or when the developers designed a character class uniform with very specific intent--say, one character in a party-based JRPG, or one race or gender in single-character games--and it looks bizarre and garish on everybody else. One of my favorite games but also one of the worst examples is Xenoblade Chronicles; the game has a lot of emotive moments and a very powerful plot in general, but it's kind of hard to take a lot of scenes in the game seriously when, say, the main character is wearing what looks like sixty pounds of electronic scrap, his mentor is dressed up as some sort of waistcoat-clad tribal warlord, and the healer is clad in a bikini top and floating Viking horns.
Some games avoid this by making wearing a complete set optimal--Monster Hunter is a prime example of this. There's no reason to dress up as a bare-chested samurai with a fish helmet when a full suit of samurai, fish, or bare-chested barbarian armor is objectively superior. Other games let you just reset or change your characters' appearances (but keep their stats the same) with an item or skill--for example, I have no regrets about blowing 800,000 pg on Freelancer costumes in Bravely Default, which otherwise would have suffered from it
very badly.
