Hello
I started a new game selecting the special outfit thinking it was going to look like a stylish samurai armour, the outfit is just horrendous and completely breaks the atmosphere, I have tried going back to the home screen and changing it to normal but it doesn't affect the playthrough I began, do I have to go from the beginning?
Yeah, you unfortunately have to restart. It's dumb, I know. I don't know why they didn't add that as an option, but to my knowledge, every game in the series is like that when it comes to alternate outfits.
I don't think you can, either you use a mod or you restart the whole game with original outfit
You can't. Once you select the costume at the beginning you're locked into it on that save file. You'll have to start a new game if you want a different costume.
I did the same thing, but decided the moment I started having control that I hated the outfit, so restarted immediately with the correct original outfit
