There’s an updated version of the “Fashion of the Wild” armor preview simulator: https://fashion-tool.github.io/botw-totk-armor/

The images are a little dark and it isn’t as neat and tidy as the original BotW armor sim, but it is still a helpful tool to decide what your armor should look like without the need to dye every single piece yourself in-game. Just mix-and-match to your heart’s content! ;)
