Clothing skin break out in bundled 3dmodel and clothes

lap.curtsy999

I purchased a 3dmodel that came with a bundle of clothes that are meant to fit it. However i have skin of the model breaking through the cloth. See image. I have tried playing with scale of clothing, but doesnt fix the problem. Surely if the product is sold with clothes they would have ensured the mapping was correctly done? Or am i missing something that i can tweak? its a genesis 8.1 model and clothes. Please see image and advise on how to fix this issue step by step. I followed the daz fix for clothes and it made no difference.

It kind of looks like the joints on the pants have been posed. Select the pants, go to the four-lined "hamburger" icon on the Parameters pane, and go to Restore -> Figure pose.
