Wasn't getting great results with milkmaid style outfits from checkpoints so I trained a little model. 69 images of white, patterned, and blue milkmaid dresses. This is my first LoRA so it might not be perfect.
I have kept it at a pretty low weight (0.5 and below) but you may need to increase it if you have other LoRAs in your mix.
Trigger is milkmaiddress. Some other common tags are white dress, blue dress, print dress. It does decently with front, side and rear view.
Note: It does seem to have trouble with interiors and I'm not sure why. Will have to find more interior images to train on for the next version. If you use outdoors in the negative prompt, that seems to help.
