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.
