Introduction
The traditional production mode is that the designer designs the popular styles according to the forecast. The enterprise purchases raw materials such as fabrics and accessories in batches, and mass-produces the garments according to the specification standards or free codes before the arrival of the season, and pushes them to the market, waiting for the customers' choice. Such products are identical except for simple colour and specification changes, and are influenced by the designer's personalization and cultivation. This production method of mass production of the same garment is most suitable for a stable and uniform clothing demand market.
With the rapid development of the economy and the continuous improvement of people's living standards, people's consumption concepts have gradually changed. People's functional requirements for clothing have turned into functional and emotional needs, and fewer and fewer consumers have the same style, fabric, and size requirements. At the same time, consumers want to get personalized clothing with short delivery times, and the price gap is smaller than that of mass-produced clothing. Therefore, the living environment of large-scale clothing manufacturers is gradually losing. The production of traditional tailor-made workshops obviously cannot meet the needs of consumers. Some powerful companies are striving to respond quickly to the personalized market with multi-variety and small-volume production methods, but the results are not satisfactory, because this is still a production method that designs and produces according to predictions in advance and does not fully express customer personality. Design and production costs are high, and new products are quickly "replicated" by small businesses. The traditional large-scale garmentization model can no longer meet people's growing individualization requirements. The consumption concept represented by diversification has brought a new round of growth momentum to the Chinese garment industry. The traditional garment industry has entered an unprecedented transition period.

Research Status and Development Trend of Garment Mass Customization Mode
If a clothing company can find a production method that meets individual needs and has fast and low cost, it can increase profits and survive and develop in a fiercely competitive environment.MC, Mass Customization is one of the effective production methods. [1] The term "mass customization" first appeared in the 1970 book of the prophet Alvin Toffler's book "The Shock of the Future". [2] In 1993, Joseph Pine II gave a complete description of the concept of mass customization, but until It has only been valued by people in recent years. [4] Mass customization was first used in the mechanical manufacturing industry and was gradually extended to other industries. The successful implementation of Levi Strauss & Co.'s mass-customized Personal Pair brand jeans proved that the production method is equally applicable to garment manufacturing industry. [5] Mass customization of clothing is an advanced production and management mode of garment enterprises that integrates garment enterprises, customers, suppliers and the environment, and makes full use of the latest research results of human beings in various technical fields. [6] One of its core ideas is to require apparel companies to produce personalized clothing at times and costs similar to mass production. First of all, it is a theory that guides garment enterprises to participate in market competition. [7] It requires garment enterprises to consider the relationship with customers from the perspective of long-term interests, and "customer satisfaction" is one of the highest pursuit goals to attract and "permanently" retain customers. Secondly, it is a way for garment enterprises to organize and manage production. It requires enterprises to provide customers with any variety and quantity of clothing at a speed, cost and quality similar to mass production through rational allocation of resources and optimization of operation process. Third, it is a guideline that guides designers in custom product design, requiring designers to take into account the individualized variants of the garment during the design process.

Domestic research status and development trends
China's clothing customization industry dates back to Ningbo's "Red Gang Tailor", which originated in Yokohama, Japan. [8] In 1896, the first suit shop "He Chang" was opened in Shanghai, and shops were opened in Guangzhou, Ningbo and Harbin. "Red Gang Tailor" combines Western advanced crafts with traditional Chinese craftsmanship to make an important contribution to the formation and development of modern Chinese clothing. [9] The Chinese clothing custom industry originated from the red tailor tailoring, and the handstitched suit customization began to evolve and evolve to form a modern clothing custom industry. [10] At the end of the 20th century, China's garment industry developed rapidly, and the custom industry went down. With the development of information technology and consumption upgrades, traditional large-scale mass production of garments could not meet the needs of consumers to personalize the pursuit of high-quality products. [11] The clothing customization industry has once again become the slogan of the development of the garment industry in a diversified form. The development of China's garment industry has gone through three stages. [12] The first stage is tailormade for the traditional costumes of the red gang tailors, such as Long Qingxiang, Hongdu, Yongzheng Tailor, Zhenzhifu, Hong Kong Shige and other 100-year clothing custom brands. They follow the traditional red gang tailoring process, using pure hand-stitching, making High cost and long cycle. The second stage is Internet + clothing online customization, such as Yibang people, Evo launched "easy tailor" online customization, Da Yang launched YOUSUKU online custom brand and other network custom brands. The third stage is Internet + digital intelligent manufacturing, such as Red Collar, News, etc., through the 3D printing logic, to achieve a data-driven industrial Internet customization platform for the Internet + manufacturing industry, transforming the traditional complex supply chain into information-driven electronics. [14] The supply chain system realizes largescale digital personalized customization of clothing.

Status and development of foreign research
Foreign clothing network customization started earlier.
With the rapid development of e-commerce, each customized enterprise has established a one-stop platform for customizing the clothing of designers, fabrics, factories, physical stores, logistics and consumers. [15] With the rapid development of digitalization and intelligence, clothing custom brands such as "Bonobos", "Indochino" and "Constrvct" have launched digital personalization based on the Internet. [16] The largest clothing brand in the United States, "Bonobos", custom products include men's pants, suits, shirts and shoes. "Bonobos" adopts the "vertical integration, multi-channel retail" online and offline virtual and integrated business model, in addition to giving customers a better customized experience, customers have three channels to place orders, including Online (Website), Guide shop (experience store), physical department store. [17] Customers can choose and try on the clothing, and select the custom styles and fabrics of the clothing on the online platform. After the quantity is directly placed, the customer data product information is converted into digital transmission to the production department to realize the production → distribution → customer's full Quick customization of the supply chain.
Canada's custom-made leader "Indochino" provides customized services for mid-to high-end online personalized suits. Customers can customize their own clothing by visiting the online mobile terminal or offline stores in New York, Boston, San Francisco, Toronto, Beverly Hills, Philadelphia, and Vancouver. "Indochino" uses a virtual inventory business model, mainly through online sales, in the form of Travelling tailor to provide customers with offline experience. The customer selects the garment fabric, style and other independent design, and then directly transfers the data to the factory for production.
Fashion custom technology innovator "Constrvct" is a customized online clothing brand in the United States. The brand launched the industry's first online software for 3D fashion design. Customers can present the 3D map of the entire garment through the 3D design interface, and design and produce the garments that are completely unique to their own original trends. Customizers can upload their favorite high-definition photos, paintings, etc. to the "Constrvct" website, use 3D design software to design their own pictures, and then choose the fabrics, styles, patterns, etc. of the clothing, and then place the order through the independent volume.
The data is transferred to the production department for production.
Digitalization and intelligent customization are the inevitable trend of the development of the manufacturing industry. [18] They are also one of the important contents of the "China Manufacturing 2025", the German "Industry 4.0" and the US "Advanced Manufacturing Strategy Plan" and other national strategic plans. With the continuous upgrading of production and demand levels, the development of digital technologies such as CAD, ERP, 3D scanning, MTM, and virtual fitting, the future apparel industry is moving toward digitization and intelligentization.
