Why does the skin texture spills to cloth texture when touching?

Is there a setting I need to be aware of?

Probably a smoothing modifier. They help clean up poke-through, but since you can't set smoothing modifiers to specific polygons or body parts, they react to fingers, for example, the same way they react to the torso.

The skin texture is not spilling, that is the figures belly.

That happens when there is not enough space between the finger and the belly for the clothing, so the finger pushes the clothing inside the belly.
