This is a LoRA I trained to give girls big fake bimbo lips.
This LoRA was trained on deliberate with a mix of real photos and digital art and works quite well with realistic and semi-realistic models.
The trigger word is bimbolips and also the words big lips and huge lips can help control the size of the lips along with changing the strength of the LoRA. I've found that strengths between 0.5-1 work well - may want to change this based on the checkpoint you use.
A couple of the sample images use other LoRAs, particularly the Big Lips LyCoris available here: https://civitai.com/models/56504?modelVersionId=108594
If faces come out messy, make sure you use hires fix if you can. Also Adetailer is a big help for images where the face is further away.
