I recommend using around 0.5-0.7 strength.

All images used to train the model had the same art style.

It is possible to change the colour of the outfit parts by just adding colors before the trigger words. However the bottom half seem to become the same colour most of the time. You might need to add some negative prompts to prevent the skin colour from changing however.

It's also possible to use the model for the art style only (by not including the trigger words for the outfit).

Trigger Words: bondage outfit, body harness, thigh garter belt, waist garter belt.
