Line refers to those bright clothes with the same style, and each set has its own characteristics in the whole style series. Most of them are independent works or products designed and produced according to a certain theme, with the same elements and more sets. The aesthetic characteristics of each series of clothing in multi-element combination are also the basic ideas of this series of clothing. Serialized products are the product of the combination of life and aesthetics. Nowadays, many garment enterprises have the trend of "serialization" and "multi-level" in product production. Serialized products not only give people an orderly aesthetic feeling, but also highlight the brand image and product style in the exhibition, which is convenient for people to remember and provide a variety of quality services, and can also avoid the embarrassing situation that consumers frequently encounter the same dress. In modern society, with the rapid development of cognitive ability and technical means, people begin to have systematic vision, means and thinking ability. The superiority of systematic design products also makes series thinking design develop rapidly in recent years and occupy an important position in modern design. Serialized dress styles have been accepted by people. Different brands of clothing products in the market are displayed in the form of a whole series on the window and counter display or on the runway display, which has a strong visual appeal and irritation with the serialization rhythm of repetition, emphasis and detail change, which is much stronger than the effect of a single product. The overall effect of clothing works or products, as well as the depth and breadth of series of works or products, are all expressed through the cohesion of various elements in clothing series. Works or products with a strong sense of series have the effect of "standing out from the crowd" when the style and popularity are in place, and are constantly favored by consumers. Series clothing design is the group design of clothing groups. In the series design of group clothing, the logic of the series is the characteristic of its series. When designing the details, we should consider the series of clothing from both vertical and horizontal aspects: from the vertical perspective, the functionality of clothing and the factors such as the composition, three-dimensional modeling, color matching, fabric texture, structural treatment, technology and contour modeling of single clothing in plane form; From a horizontal perspective, it is mainly the logical relationship between a single garment and a series of garments, that is, the logical relationship between straight and straight dividing lines in garments, the logical relationship between the contrast and coordination of TINT, the logical relationship between fabric texture changes, the logical relationship between garments and clothing in design colors, patterns, jewelry "* * *" and "personality", and the unified relationship between clothing and clothing style. As a society, people must also consider the relationship between clothing and people, clothing and living environment, and the overall coordination of clothing. It can be seen that the series design is to study the logical relationship between each group of clothing, the image of series clothing and the style of series clothing in the whole design, which is also the characteristic of series clothing design.
