Ghastly has a Male Catsuit, but it doesn't fit the P4 Male unless he's got "superhero" set at 0. It won't work with any other P4 Dork Muscle Morphs. However, there is also a bodysuit for Mike... you can make a transmap for it to hide either the upper torso entire, or turn the upper torso into the tanktop.

Remember, kids! Napalm is Nature's Toothpaste!
