This model is designed to show backlit dresses showing the silhouette of the woman's body. Known as WtSSTaDaMiT (When the sun shines through a dress and makes it translucent). First off, I will say I did some testing, and it seems like this doesn't work great on illustrated or anime style checkpoints, but still give it a try for yourself! I don't do much anime style images, I mainly work in photo real, so I might just not be prompting it correctly.

Flux Dev model info:
This one just uses the trigger word "TransparentDress" due to how it was trained.

sd.15 model info:
Second, there are 3 different prompts you can use to adjust the style of the dress
1. Trigger word "Transparent Dress" this will make the dress more see through and make it more nsfw
2. Trigger word "See Through Dress" this will make it a sheer material, less nsfw than the previous
3. Trigger word "dress" it will just be a normal dress but the sun will still shine through it.

Experiment will all three to see which works best for your situation!
