Layered clothing issues?

Currently I’m trying to work with different body types -

We have R15, S15 and Inf15 -
Ideally I’m looking to use Inf15 as it has smooth edges and is proving to be more performant friendly than S15 - However, I currently have the issue where layered clothing aren’t the most appealing and seem to be warping -

Note how R15 and S15 have similarities and indistinguishable however the Inf15 on the far right has an extreme warped effect (This occurs with all layered clothing.)
Is there any way to adjust the initial model to allow for smoother attachment?
