Let’s see how to draft the pattern of this trendy blouse.
Start from a basic block with darts and basic sleeve.
On front and back draw the underbust line and a parallel line few cm below the waist one.
Draw the back neckline.
On front, widen the waist dart by 0,5cm on each side at the underbust line.
On the sleeve, draw the cuff and the new and wider sleeve bottom.
Trace the separate pieces: back bodice, front bodice with dart manipulation (closing the shoulder one and opening it at the underbust), back and front waistband with darts closed – draw a couple of horizontal slash lines on them – mandarin collar with a slash line also, cuff and sleeve – draw and cut a T slash line at the cap to open some volume.
Cut through all the slash lines and add few cm paper in each cut.
Redraw the shapes and mark the gatherings.
Add a rectangular piece for the bow and your pattern is ready!
