Welp, I decided to bite the bullet and go back to Belle's swimsuit mod to make fixes for 3.0. Through the process, I decided to just get all of the previous mod versions and combine them. It would have taken just as long or longer to fix all of the previous versions, anyway.
So, this has the following options built as toggles:
-Body sizes
-Body accessories
-Shoes
-See-through shirt
-Nipple piercings
(Hat and hair accessories were not touched because they are meant to be changeable with the in-game accessories system. This means you can swap out the hat, for example, with multiple different hat/ear options. But this also means you can't having nothing on the head. Something is on the head at all times, which is the compromise.)
I did change the body just slightly, making two body size options, one that is slightly smaller than the original, another that is slightly larger. Additionally, I slightly reshaped the breasts and added an even smaller toggle option.
Hopefully there's not some future update again that breaks Belle like this 😭
I guess that's the cost of modding our little Belle!
I wouldn't say this mod is up to the standard of my current mods, but I still think it has its own charm. Give it a try!
