Looks like the transparency on some mods got broken again in 4.1 Update.
You can basically attempt to fix these by juggling the match first index numbers in the .ini files for the different head/body/dress/extra sections. This will apply to any broken transparencies - on mine or other mods.
For Rosaria CN (her regular skin seems to be working fine still), copy and paste this into her .ini file... You can also try using the ones in her .ini.
This will be for her latest mod with the transparent bikini... it might work for earlier versions as well - no guarantees as I haven't tested. Worst comes to worst, move those numbers around yourself and some combination will probably end up working!
