Maybe so, but Rainman almost always uses the narrow shoulder for the tailoring. He even did that with Pee Wee where there Slim would have been a much better option (presumably because the Slim was very hard to find at that point). One exception is Marty McFly, but considering that the Advance was very hard to come by when Anton went up for pre-order, I doubt seriously that Rainman used it to tailor the outfit. And any other body will probably make the outfit look a bit awkward on the figure.Oh so that should be perfect!
