For me, one of the problems using Stable Diffusion is that when I want to generate a character wearing tokusatsu or sentai bodysuit without helmet, the bodysuit often doesn't fully cover the neck skin even "turtleneck" is added in the prompt
Personally, I CAN'T ACCEPT THAT
This Lora tries to fix the problem but it's not perfect
Trigger word: covered neck
Also add "(color) neck", "(adjective) neck" if necessary
Weight: 0.8-1
Recommend to use with ControlNet Canny. For details, see HERE
You can use it as usual, but it may change the output of the image completely (this is the biggest issue)
It was not tested on male characters. It may work fine or not
