I wanted to give clothing training a shot, especially since it is supposed to be the hardest type of training... I must have trained this model about 13 times! I tried my best to get all of the characteristics of the jacket into the model. Unfortunately, there aren't many cosplay photos where the jacket is a 1:1 copy of what we see in the Cyberpunk 2077 game. I have a replica of the jacket that is somewhat close that I was able to get a few pictures in and add them to the dataset.

For the strength, I would go around 0.75
It helps to name the color of your jacket. (brown for the game version)
Also, if you are doing "from behind" pictures, it is best to list the color of the person's hair as well.
The backgrounds tend to be slightly blurry (I don't know why). The SDXL Styles add-on for a1111 seems to help flip this into other styles. It's not as flexible as I hoped for it to be, even after 13 trainings. It is very close though.
