Out of curiosity, does Meggan actually wear clothes? Or is she essentially naked and just manifesting part of her body into the semblance of clothing like Mystique does?
If Meggan has no actual clothing or, her limited human clothing would be torn apart as soon as she metamorphs into anything beyond a pixie blond's physique... then Rogue could touch any part of her body to absorb her power.
Unless Meggan can metamorph her body and manifest armor that would negate the skin-to-skin contact Rogue's mutant ability requires?
