CC Clothes Weird Bug

Hello @RuthAnn107!

For the men's underwear/swimsuit, the fix might be to run the Sims 4 Studio batch fix for underwear tags. You can download Sims 4 Studio here:
http://sims4studio.com/ (membership is required but free) Once you have it installed, from the main page choose Tools from the menu along the top then Batch Fixes; CAS; fix male swimsuit/underwear EA recolors missing mesh

You can use also Sims 4 Studio to find your other broken files. On the main page choose MY CC. A new window will appear and on the left will be a list of all of your CC with a window to show the creation. You can then look each file to see if it is broken in the window. The program has a delete button if you chose to delete the file from your game. If you want help finding the original mesh, just tag me @Bananas_45 and include the name of the package file and I will see what I can do.

I know for sure the wedding dress is curbs_DressWedding_7_RECOLOR_2.package and you can download the original mesh here:
https://www.thesimsresource.com/downloads/details/category/sims4/title/wedding-dress-7-%28original-mesh%29/id/1379339/

You can also use Sims 4 Tray Importer to identify broken CC. You just need to make a sim wearing the broken CC and save to them to your gallery, then you can use the program to see the files used and remove them. Again, if you want to provide me with file names, I can try to find them if they have enough identifying info in them.
