The neck opening of 0-0.3cm is spread. Then use

As a base point, rotate

Part of the opening is positioned at

Here, the shoulder was spread to a shoulder looseness amount of 0.1 cm.

Including shoulder line portions, to

Clockwise rotation as a base point, and the development amount is 0-0.6cm of muff looseness. Then, the product is processed

(including shoulder line portions) to

As a base point, transfer

Here, the developed amount was 0.1 cm. Then will be

(including shoulder line part) is respectively rotated and unfolded by 0.2 at left and right sidescm, 0.1cm (shoulder looseness).

And

and correspondingly.

Rear sheet:

to be provided with

As a base point, it is developed counterclockwise by about 0.1cm (neck opening looseness), as shown in fig. 15,

in part by

Rotate counterclockwise for the base point at

Twice, the size of the unfolding amount (muff loose amount) is generally larger than that of the front piece

To (3).

Corresponding front piece

The amount of deployment.

Part of the lower left side is spread upward

Same (shoulder looseness).

2. The tightness and waist distribution of the body

The front clothes body: as shown in fig. 16, the lateral split collar is large,

the position of the BP point is deviated.

The size of the provincial road is 1.5-2.5cm lower than BL, and the other provincial cusp position is positioned between the vertical heights of the two provincial roads of the prototype. Side seam

There is a waist-tightening amount. With BP and

and the middle point turns all the provinces to the lower hem.

The back clothes body: as shown in fig. 17, the lateral neckline is spaced apart by a distance equal to the front panel,

the two provincial lines are not overlapped and can be transferred to the armhole nursing position. Way of province

The upper sharp point is between the prototype sharp point and BL, and the lower sharp point is between the vertical height of the two sharp points on the two sides of the prototype.

With front garment piece

And (4) symmetrical. The convex line behind the scapula extends to the arc line of the sleeve mountain to be used as a dividing line of the york.

Example 2:

as shown in fig. 18, which is a front and back pattern of a four-open suit (pattern two), the collar is designed as a lapel collar, and the sleeves are two bent sleeves.

1. Expansion of neckline looseness, shoulder looseness and armhole looseness

Front panel: as shown in FIG. 19, shoulder dart is first revised, and

and moving the provincial cusp BP' to a BP point, and correcting the provincial road line.

The part above the chest line is translated upwards (influence of the thickness of the cloth),

the part is made into the parallel line of the front central line (influenced by the thickness of the cloth) and is surrounded by the collar

The amount of transfer (neck opening looseness) is 0-1 cm. Then will be

And the portion between the chest line shifts to the intersection of the side stitch and BL line.

Is the position 4-5cm below the shoulder point on the armhole line,

spread in the vertical direction with BP as the base point, and then spread

In order to shift the base point in the vertical direction,

and

all spread out in the vertical direction.

Rear sheet: firstly, the method

To save sharp points

Translate to the right onto the armhole arc and then on

Parallel lines (influenced by the thickness of the fabric) with the distance of 0-0.1cm from the central line are arranged outwards,

is the protruding point of the scapula,

is 4-5cm below the shoulder point on the armhole arc line, and

the same distance from the shoulder point. As shown in figure 19 of the drawings,

the portion above the two lines is translated upwards by 0-0.1cm (influence of the thickness of the fabric).

As shown in figure 20 of the drawings,

to be provided with

For the base point transfer, the transfer was performed at the same position as the front sheet at a ratio of 3:2 as shown in the figure.

Near the part of the neckline

The base point is shifted upward by 0-0.1cm (shoulder looseness), the left side of the part close to the armhole line is shifted upward by 0-0.1cm (shoulder looseness), and the right side is shifted upward

The position is 0-0.2cm upward (muff loose).

Of the body

To

The protruding line of the scapula is arranged between the two adjacent scapula,

before processing for prototype

The position of (a). The armpit point of the coat body is 1cm lower than the BL line, and the armhole arc line is redrawn. Will be provided with

The part above the spread line moves upwards to offset the influence of the thickness of the fabric.

2. The tightness and waist distribution of the body

The front clothes body: the transverse collar is 1cm in size, as shown in FIG. 21, and is divided into two parts

Is positioned about 8cm above the BL line and avoids the BP point, wherein

The point is the BP point a given distance to the left. Distance of dividing line

About 1-1.2cm in length,

size of Zhou province2-2.5cm, and making a smooth dividing line downwards.

Then taking BP as a base point, will

Is closed, thus forming

The dart point is at the dart path of BP, and the dart point is moved 1-2cm obliquely upwards because the dart point is easy to cause small protrusion at the BP position at the BP point and the visual effect is not beautiful. Thus, the shoulder area is completely transferred to the small area of the chest.

Front side clothing body: the right side cut line is split from the cut line below the BL starting at the front panel,

and

and (4) oppositely. Aspect ratio at division line

Slightly larger.

The back clothes body: 1cm wide in transverse collar opening and front sleeve cage dividing point

With vertical distance upwards of 1-2cm

As a division starting point, the position and size of the division line are close to the dart of the prototype whose rear piece is large. The back waistline is contracted by 1-2 cm.

Rear side clothing body: the radian of the left side dividing line is smaller than that of the opposite dividing line of the back clothes body, so that

Upward by a certain adjustment amount

To balance the length of the two-day intersuture curve.

Example 3:

as shown in FIG. 22, which is a front and back pattern of a three-part suit (pattern three), the collar is designed as a banquette, and the sleeves are two bent sleeves.

1. Fig. 23 is an expanded view showing that the neckline looseness, the shoulder looseness and the armhole looseness have been completed.

2. The tightness and waist distribution of the body

And (3) the outward extending dimension looseness of the left axillary point and the right axillary point is measured, then the two points are overlapped together, a vertical line, namely a side stitch line, is made downwards, and then the drawing is carried out according to the clothes length and the waist length. As shown in FIG. 24, where the waist length is determined as the prototype between the waist line of the rear panel and the hip line, the central back waist point coincides with the central back waist point of the rear panel above the waist line, and the perpendicular distance from this point to the hip line is the waist length. The front and rear pieces are respectively opened with a large transverse collar, and the armhole deep line falls. The body BL of the garment is higher than the waist line of the prototype, and the garment effect can prolong the lower half proportion of women and is in line with the aesthetic sense of the current public.

3. Distribution of provincial and division lines

The size of the province road of the front garment piece is set to be 1-2cm, the upper province sharp point is separated from BP, the position of the lower province sharp point of the province road is between the vertical heights of the province roads on two sides of the prototype, and the shape of the province road is thin and vertical province. The dart size of the division line at the waist line is the dart size of the prototype on the right side of the division line.

The oblique line is the position of the pocket, as shown in FIG. 25, the dart at the position can be moved to

Then will be

The shoulder provinces are merged and connect the neck side point and the shoulder point.

The waistline of the rear garment piece is 1-2cm, and the rear garment piece is divided into two parts

The position and the size of the position are similar to those of the dart at the position of the prototype, and the starting point of the dividing line is on the rear armhole line and is higher than the vertical height of the front piece dividing line. The way saving amount of the shoulder is relaxed, and the sewing shrinkage treatment is carried out. Side cut piece dividing line

The cuff line and the segmentation line are trimmed after the left shift.
