I have this issue also. When I choose "change outfit" all the outfits have been replaced with outfit 1 for the category. For me it seems to happen during gameplay after several sim days not when I load in so it might require some play time to replicate. I have mods but I have tested and this happens with mods in or out. It only started in the past 2 days. The save it happens in is from after the big c&d patch but before the actual expansion came out. I tried with a new save and haven't gotten this bug but did get the other outfit one in that save where they just wear something random instead of a preset outfit.
Would you be willing to share your save with me ?
If so, please zip your saves folder and upload it somewhere like dropbox, mediafire, googledrive or OneDrive and PM me the link.
