Not much to say, I did some experimenting with Pony Loras and created this fire fighter uniform Lora.
The trigger is pretty barebones: EPFireFighter, wearing EPFireFighter is enough but you can add more keywords to modify the outfit, e.g. jacket, pants, harness, helmet, ... play around and see what you can get out of it.
The outfit does yellow and brown jackets & pants without any problems (but other colours work as well,) just prompt, e.g.,
pants, brown pants, same helmet, red headwear, red and yellow work very well with the lora but also other colours. Use no headwear if you don't want the character to wear a helmet. Just experiment a bit and see what you can get out the lora.
Feel free to leave me a tip if you like what I am doing :)
