As scorpio64dragon says, Victoria 4 is the generation before Genesis. If you are only using the V4 figure that came with the V4 Pro bundle, then the BodyBuilder morph would need to be built into the clothing to work out of the box. In DS3 there was an option to use Morph Follower which will tranfer morphs from the figure to the clothing for you. A similar method is available in DS4 and is called Transfer Active Motphs, which should put the BodyBuilder morph into the clothing you are trying to apply.
Genesis is the latest generation of figures (Generation 5), and can be motphed into almost any shape. The clothing automatically adjusts to fit the Genesis morph in most cases. The V4 shape that scorpio64dragon has given a link to is just that, a shape that makes Genesis look like V4, but it is still a Genesis morph, and not a stand-alone figure like V4.
