In the clothing changes in style, you can use a wide range of buttons, the designer must be based on style, as far as possible before reference to the median position, the highest and the waist position to design.

The upper eye position in the buttonhole is the most important. Should be marked with the horizontal line of the base line of the refutation line (the refraction line passes the x-point).

Waist button is also very important, it is often located above the waist line, waist line can also be located below. In the connection-type jacket, only a buckle (connecting double button), it is always located in the sub-2cm above the waist line, to prevent the refusal arch. Most of the current models use the middle button, or the lowest button, and in the traditional style, narrow split head suit often used high-button. Two buckle more convenient, according to the style of buttonhole spacing, the general buttonhole spacing of at least 6cm (sometimes less), up to 1.5cm (usually 9 ~ 10cm).

In a single-breasted style, the distance between the button and the buttonhole to the corresponding edge is theoretically equal or substantially equal. This is particularly suitable for narrow placket (2 ~ 3cm) style, because here, the button means that the front midline. In fact, the buttonhole is usually very close to the mouth line, about 1 ~ 2cm, while the buttons are often sewn in by the mouth side of the side (preferably sewn in the stack door), and sometimes inward or outward movement, To adjust the tightness of the garment. In this way, we do not have to move the distance before the midline (such as high-bit suit jacket).

In the double-breasted style, double-button away from the front center line distance, mainly by the width of the placket decision. This style is usually a wide split, the new position below or higher than the waist line. For the low-head, low-nu-bit traditional style, the distance is usually 9cm, or even 10cm (and the button spacing is 14 (the button spacing is 10 ~ 11cm); ~ 15cm).

When the design of double-breasted suit jacket buttons and buttonhole, the buttonhole on the placket, usually from the edge of the mouth marked 1 ~ 2cm at its location, and then, in order to facilitate sewing, the opposite side of the amount measured from the front center line Distance, to determine (by the inside) of the second new line (of course, in the line of the inside without a buttonhole). On the sole, the single-breasted eye is usually closer to the button than the closed button, so that the bottom edge of the lower door is held in place.
