Need help for cloth simulation on human model

I start cloth simulation on a human model with normal size, but there is a gap between cloth and human, as shown in the picture. I minimize the distance in cloth collision. I don’t get a good result. I don’t want to scale the model, because I need to make an animation a real-time cloth simulation on a character.

did you also play wit the inner and outer settings of the “softbody and cloth:” settings for the collision object?
Before simulating again change a value under cloth sim and set it back to the value you had before… Thats because blender needs sometimes new input to calculate new settings for simulating stuff and “refresh” everything… Hope that behavior will end in future. And also make sure every object has scale of 1.00 for x,y and z. if not it can also end up in strange simulations… hope it helps.
