Thanks, MrsFlynn, I tried to reset the sim and didn't make any difference, also reset the town. I have never used custom content on my game and I'm not really sure what was the point this started to happen, I kind of ignored it until it spreaded too far Dx.
At the very least, I was able to erase the buggy everyday outfits in Plan Outfit CAS screen, it seems that every time I delete a current outfit, the game replaces the slot with the weird ones and there can be deleted too until there is no more. The only drawback is you have to build all your outfits again every time that happens.
It seems there is something wrong with tatooing and getting makeovered at the salon, those where the instances where my sim would get extra outfits with exactly the same clothes they where put on on salon or on tatoo screen, before they get scrambled every time you wear such outfits.
I'll stick to that solution as needed, thanks again.
