Usually, in general with games, I dont like to diverge too much from the default outfit, feels non-canon and I like to establish the iconic classic "look" of the character first playthrough before going into wacky outfit territory. I want the real outfit burned in my mind.
But with Stellar Blade its clear you are suppose to diverge from her starting look. There are so many outfits, hair changes, even your crew gets some outfits. So I decided to embrace going with the flow of the wind let my playthrough be unique with wearing whatever I want, and swapping outfits for the crew as well. Im glad I did its fun. Maybe I should have this mentality more often for games
