Big, comfy, cotton knickers are by far the best for avoiding vpl. I've tried them all, multiple thongs, the very thin ones sold as no vpl but apart from the obvious advantages of being big comfy and cotton, the big ones are by far the best. You don't want elastic around the legs , so shorts best and they need to be maybe half a size bigger than you think but definitely the way to go.
IMO they look better than fancy pants without clothes too
