This Lora can help to make a situation that makes age younger, and clothes looser. When weight sets LESS THAN 0, the effect will be STRONGER, when MORE THAN 0, it will be CANCELLED.
trigger word : age regression
It can work with other Lora. but the effect, especially to make clothes baggy, depends on each model and/or a Lora. Loose closes like robe gets good results, tight one like swimwear is not much. Some lora should accept weight even less than -1.
Some additional words might help to make detail situation : child, oversized clothes
Actual target age also help it.
To cancel too large head, "chibi" on negative prompt to help it.
