Played Sim creates new outfits

Hi everyone, I’m having an issue where my Sim keeps changing into different outfits that I didn’t set. In Create-a-Sim, I choose specific clothes and colors, but once I go back to live mode, my Sim is wearing something completely different. For example, I set a purple knit sweater, but in gameplay it turns white or switches to another outfit. I’m not using CC for this outfit (it’s from the base game)  but the problem still happens. I already tried editing the outfit multiple times, but it keeps happening. Is anyone else experiencing this? Does anyone know how to fix it? Thanks in advance!
