This is the main mod that you should have that brings a massive amount of Zelda armor to the game. Much of the armor is hidden behind dying armor that you've acquired, so definitely make sure you experiment with dying your armor! When installing, you'll have the choice of the normal "Link" animation when running, or a version modeled after the way Zelda runs in the cutscenes
Zelda's Ballad [The Legend of Zelda: Breath of the Wild (WiiU)] [Mods]
Also on that page is an "Shield Fix." Install that so Zelda's shield is a little lower and doesn't clip into her longer hair.
This is a pretty huge mod that changes the story to be as if the game was made to portray Zelda as the main protagonist instead of Link. It also includes a fix for the gate check (since she is a Voe), re-edited cinematics and all dialogue and story. Eventually, Zelda's Ballad will include their own version of a story rewrite, making this version optional, but for now, it's fairly essential to get the full "Zelda" experience
This mod allows you to increase the amount of armor pages that you can see in your inventory. Since Zelda's Ballad has SO many different armors, this is especially useful if you have multiple versions of the same armor just dyed differently (in Zelda's Ballad, the dyes are sometimes completely different meshes too, not just color replacements)
Armor Limit+ [The Legend of Zelda: Breath of the Wild (WiiU)] [Mods]
This mod Changes the Champions Tunic, Hylian Trousers and Amber Earrings (Hairclips) to the model found in Age of Calamity for Zelda. It's really not much different looking, but it's up to you whether you like the "official" Nintendo version more. It also includes a short haircut seen on the Zelda BOTW 2 trailer
