I found an outie belly-button mod that works pretty well.
Hasn't been updated for seasons clothing categories, though. And I have no fucking clue how to do it.https://simsworkshop.net/resources/xld_sims-bodmod-outie-belly-button-3d.2532/
I actually use that one already. lol
Is there a lactation mod out there? That could be another one to make…
