Let’s draft the pattern of this trendy top.
Start from a basic block with shoulder dart. Mirror both back and front.
Redraw the right shoulder and armhole and the asymmetrical neckline.
Draw the slash lines for manipulating the shoulder darts to the side.
Draw two parallel lines (above and underneath the waistline) to define the waistband.
Cut through the new style lines, close the shoulder darts on the front and open them in the sides. Get also the two separates waistbands.
Merge the two waistbands and extend the new piece to be able to tie it in a bow, add front and back and your pattern is ready!
