This Lora creates pregnant woman with a sexy skinny body.
It works with various art styles, but I think a checkpoint with a more semi-realistic style is better to show the fine details of the skinny body, like ribs or the slender limbs.

It looks best with small and medium sized breasts, but you can also try larger sizes.

The Lora strength depends on the used checkpoint, please try out different settings to find out your preferences.

Recommended settings:

Strength: tested with 0.8

Triggers: pregnant, skinny
Optional triggers: collarbone, ribs, sagging breasts, other tags that emphasis a skinny body
