There is a tremendous amount of information that is lacking from the OP.  This is their first post and there are too many assumptions being made.  As far as I can ascertain, the OP may not have conformed clothing correctly and is essentially seeing the figure move and not the clothing resulting in pokethrough. 

@ makis12: you will need to provide as much thorough details as possible.  Speculation will not adequately answer your questions or issues.  Provide which Poser version you are using, what type of clothing you are attempt to dress you model, what is your workflow, etc.  More details will help us help you quicker.
