I've always wondered, how do you guys determine fit when all you see is barly half of his torso, a raised arm, and a cockeyed tie? Because to my eye, the right shoulder, which is all you can see in this picture really, looks to be a little large. But it could be how he's holding the camera.
Shoulder extension (up to a certain point, obviously) is a stylistic choice. Really, it doesn't seem excessive in that picture. Fit is determined by whether the armhole sits at the right place or not.
