I did it for the tunic on my Obi-Wan and regretted it because it did shrink. I haven't had any problems with other figures I have done it on but this one has little pleats in the fabric. They shrink up funny somehow and when it dried, it did not hang the same. Now I wished I hadn't done it.
When I did mine, I took the tunic off, wet it and put it back on.
