What I do not understand well: the seam at the center front - looks at the top not absolute. Here I would have wished it on the side or rear, where you can not see it, at least so directly. The gap in the step seems to me illogical that. By two superimposed pieces of fabric that are not sewn up there On the rear fabric piece holds a panty liner, on the front not. I have further away the underpants, to someone you liked and fit.
