A lora for a traditional Japanese bridal outfit, including the shiromuku white kimono and the wataboushi headdress.
To my shock and delight, the headdress is actually pretty stable, it doesn't need much fussing. Occasionally it will generate partially see-through, but this is easily corrected by adding "translucent" to negatives.
It does generate the (generally red) colored accents on its own, but if it's giving you more white than you want add "red accents" to positives. (Or, y'know, whatever color.)
Given the likelihood that you'll use this for a wedding-related scene, note that SD loves to throw the western-style dress in with that, so adding "kimono" to positives and/or something like "ballgown" to negatives can clear that up for you.
As an experimental bonus that I can never seem to resist trying, it does recognize "holding shiromufa dish" as a trigger for the red wine bowl used in weddings. I really didn't refine this, so it's only so-so in accuracy. Adding "food" to negatives helps.
Hoping to update this one in the future with the other traditional wedding headdress as well, but it's significantly more annoying to source data for, so be ready to wait a bit for that one LOL.
Now go forth, and... make your waifu an actual waifu? Idk ROFL.
