I’m not sure I totally understand your question: do you mean other lots without the “clothing optional” trait where I put my Sims in the nude outfit and ask them to get in the sauna or go yoga? The only lot I have tried that on is their home. And (with or without the lot trait) they do the same thing: if I have placed them in the “nude outfit” they change out of it into a towel for the sauna of workout clothes for yoga. (They will of course skinny dip in the hot tub but there is a separate and specific action for that). Does autonomy matter I wonder? It’s not a big deal at the end of the day but it seems odd that NPC’s run around the whole spa naked and my Sims keep popping in and out of garb from room to room, even when I manually placed them in nude outfit mode.
