I wanted this type of dresses, so I started collecting images, but it didn't give the result I wanted, I ended up using a 1.5 SD model, to generate images and use them as a dataset, this was the result.

It has many flaws (too many flaws), it does not generate good transparencies and it is quite difficult for it to generate ??????? under clothes, as well as pubic hair, later I will try to make a better one,

To change the color of the outfit just type "color dress"

I leave the dataset free, in case someone wants to remake or improve it.

Thanks to @AIadoreyou for his recommendations, the model now works much better!
