Made for a bounty.

OTM = over the mouth, by the way for those who don't know.

Include both OTMbandana and OTMgag-white tags, though can change white to red, blue, grey, brown and it should still work. Not sure if other colours will work, and the hit rate with the colour seems lower on colours other than white.

Seems to work well enough with a style or character lora, but needs high a strength setting to work, ideally 1.0. Hence might not work so well with a ton of other loras at once (where you typically have to reduce the strength of all).

You might want to add eg "mouth, lips, teeth" in the negative to help too.
