Awesome LoRA for clothing! Focused on dress and girls, like, well, always.
It is much easier to use as a standalone LoRA. If you want to use with a character Lora, you must use a low weight (so the LoRA weights not related to the clothing don't blend on your model)
and emphasize the words related to the wanter clothing.
Example: <lora:wrenchsilverserenade:0.5› (wrenchsilverserenade, gown, shiny silver (metal) dress:1.6)
It WILL blend to some degree that you may accept or not.
