Had to reinstall all of them and back up my save, but:
Baby bib
Skimpy Nurse Top
Every Underboobs Top
Every Happi Breast Band
Virgin Killer Sweater Full Body
Every Ribbon Bra
Christmas Bra
Every Sailor Bikini Bra
Sexy Nurse Shirt
Sexy Sailor Suspenders
Latex harness is bright glowing pink for some reason. Probably intentional, but weird
Everything is listed in the store twice for some reason
And that's not getting into all of the tops that are incompatible with any cup size below H
Sorry for the late reply, just manage to open my PC and SFM to test the issues based on your save file. So basically most outfits will have clipping issues especially if Manaka's breasts get too big or too flat. To fix the nipple clipping issues (regardless of any breasts size), you can insert "isFlattenTit":true code into the descriptor.json file in ModCosplays. I will quote myself here, there is an image example in my original quote, feel free to refer:
Oh yea, one extra thing, in case Manaka's nipple clip through any outfits that does not support chikubi shape key, do use the
code in descriptor.json of the specific outfits in the ModCosplays. That code hide the nipple so that it won't clip through the outfits. Not sure had anyone mentioned it before or not, but oh well. For example:
I tested it with a few of the mentioned outfits and it work so far, so hope it help.
Meanwhile, Baby Bib, Skimpy Nurse Top, and Latex Harness is not imported by me, but the nipple clipping issues should be fix by using the "isFlattenTit":true code. As for the everything is listed in the store twice, I not sure what caused it... probably a bug but I couldnt seem to replicate it even through your save that I downloaded before you delete it. It ok, I will not keep your save in my PC, deleted as I posted this reply.
Anyway, hope my message help, and sorry if I yap too long XD.
(Edit 1: Extra
For outfits that I imported, I might not include the "isFlattenTit":true because some outfits did support chikubi shape key, but yea, feel free and please add in the extra line of code to those outfits that have the nipple clipping issues, very sorry for troubling you or anyone in the future.)
