Over one year after training a LoRA for SD1.5, I've got a new model of Jessie's style of uniform for SDXL (Pony-v6).

pencil skirt, zettai ryouiki, puffy short sleeves,It's trained on the base PonyDiffusionV6XL, but testing it at a weight of 1 it works on both Pony and the Autism mix. It doesn't work very well when generating the backside of the outfit though, as it tries to put the R on the center of the character's back.
