When cutting clothes, you must first calculate the material. The width of 1.5 meters is about a piece of cloth 10 cm long. Cut vest skirt first and draw a horizontal line on the paper. The length of the horizontal line is the length of the skirt.

Draw a vertical line perpendicular to this horizontal line at both ends. Then determine the collar, my skirt, the collar width is 22 cm and the collar depth is 13 cm. It is a rectangle. Then connect the upper right corner and the lower left corner. Draw a vertical line from the upper left corner, perpendicular to the line just now. Find the finish line. Connect the midpoint and the point in the upper right corner with an arc. Click on the lower left corner. It forms a round front collar.

Next, determine the shoulder width. . It is 39 cm away from the lower right corner, which is 1/2 of shoulder width. Vertical five centimeters to the left, which is a fixed value.

Lumbar joint line, lumbar joint 39 cm. From this vertical line on the right, measure 39 cm to the left, perpendicular to the horizon, which is the waistline.

Draw a bust line perpendicular to the bottom from the right. The algorithm of bust line is 1/5 bust minus the intersection of 1.5 bust line and armhole depth line.

Draw a smooth line from the shoulder point to the depth of the armhole. It's the deep line of the front armhole.

Waist line is 39 cm, skirt hem circumference is 6 1 cm, measured from bottom edge 6 1 cm. Connect the waist line with the length of this point. The bottom is two centimeters upward. Connect this point to the point of the center line of the skirt to form an arc, which is the skirt.

The width of the neckline at the back of the skirt is the same as that at the front, and the depth is 2.5 cm. If only it were a picture.
