Oh I see that option with morphs now, I was looking at the wrong place in the menu for it.
I am getting a weird behavior with outfit and hair though, it's not a big deal, but every few in game hours i get a message telling me that i'm wearing a bad outfit, and then a few hours later i get a message telling me i'm wearing a good outfit again (this is despite not changing outfits). I'm using the bimbo mesh outfit too.
I also get a message telling me my hair has grown to (none) and then says your hair has grown to bald, and then a short time later i get the message your mod generates telling me hair has grown to classic length. This repeats too.
The only thing I've done different I can think of is I turned on the old in menu YPS hair control system which lets you either set hairs in the defaulthair json, or use the fields for hairstyles in the MCM (the new system uses the hair database json I mentioned).
I'm wondering if the check for hair length from your mod doesn't work with the older system, and it's somehow confusing the clothes check too?
It's not really a big deal, just impacts immersion but I figure I'd mention it in case some bigger issue comes up and it helps you troubleshoot it.
edit; none of the above actually changes the hair length, it's just these are the messages posting in the upper left side of the screen.
