You can add your custom outfit to KDModelDresses, then add outfit: "YourOutfit"
For reference, check KDModelDresses, KDModelHair, KDModelFace, KDModelStyles in resources\app\out\main.js
The ingame outfit name can be found in Text_KinkyDungeon.csv
I suggest using Visual Studio Code with GitHub Copilot and let it do the work for you
