Just me ranting about shin guards: Okay straight away let me just say this. I have no idea how Ai is unable to create her Default Outfit's shin guards. I've done multiple testing and re-trained it, but shin guards overall just don't appear... Maybe in a case where you train only on her Default Outfit it would've worked, but well... I have 6 outfits here...

The results of your generations are dependent on the additional LoRAs, weights, and models you use, so it may not work or come out as consistent as my sample images.
