Ruth (dark hair, purple clothes) and Esther (light hair, pink clothes) from Futurama.

Since they always appear together decided to do a single lora for both of them. Does a good job of generating them together, while keeping the costumes, hair, and facial features accurate to each one. When prompting them together it's better to use less details, and letting the model do it's thing as it knows the outfits.
