Wearing heavy armor is fine and all, and that you can’t go out into battle in your town clothes(lest you’re an engineer, but that is medium armor) I get.
Even if entirely cosmetic, it would be nice if there there was a an “outerwear” option, like a simple robe with a hoodie, a robe, a cape, to be worn on top of your armor. In fantasy novels, westerns, sci fi, when travelling our heroes often find themselves wearing some sort of robe/cape. Hell, Clint Eastwood wears that bad*ss cape over one shoulder in a Fistful of Dollars. Jedis’ got their robes. And you don’t have to look far to find more examples.
It could be entirely novelty, or stats could be added. I realize that there is workings on cape for guilds, with clipping issues. I still think that it could be an idea to look into.
