Inspiration for jumper or cardigan if cut down the middle? And I might cut up and lengthen the inner sleeve seam, this creating more of a side seam at the same time so it's not quite so revealing on the sides.
Smunch/ front pleat top - burdastyle pattern ~ very stylish way to draw up a neckline to a simple "bag" top. Looks to me like two rectangles sewn together up the sides and at the shoulders. Front rectangle wider than the back to make the pleat.
