Snake Eyes was a legitimate issue. The lycra top just didn't flatter the shape of the Pro's torso and it's tiny middle-abdomen, oddly shaped muscles and thin joints. He may as well have just been shirtless. Storm Shadow is a non-issue. The material covers his arms and is thick enough to adequately hide the oddities that made Snake Eyes look so bizarre.
That said though, I'll never get why people think that ninjas should look like those Hawaiian muscle warrior shirts.
Not all ninjas, just Storm Shadow
