Everything LF2 is sporting in this render is dynamic, the sweater, the jeans, and the hair.

                                                                

We need to pinpoint where you are having problems.  You have been reluctant to share your simulation setup, and it is difficult to determine how, where, and why your problems are continuously repetitive.  Do a series of screencaps of what you are doing in the Cloth Room, from basic setup to final pose.  Capture images of all the open panels and what you are doing in each.  Document your procedures, otherwise, you will continue repeating the same mistakes.  You should have results similar to those posted above by now.
