The clothes, like many, are autofit, but also has Deforce, also like many, the creases are from the auto fit where Daz is fitting the morphs to the clothing and doing a rather crap job, running deforce doesn't correct this issue sadly. the only work around i have found is to set Genesis 8 females breasts to completely flat via the morphs at an animation time line of zero, then setting G8F's breast morphs to the chosen size at frame 30 then running the deforce simulation to include all frames in the animation. this doesn't help with clothes that are NOT deforce, and as such i have no workaround for those clothes where the breast morphs are incorrectly applied to the clothes.

Getting old and still making "art" without soiling myself, now that's success.
