In China, the popularity of "oversize" style can be traced back to about 20 10 years. The popularity of this style is mainly influenced by the international fashion industry, especially the street fashion culture in Japan and South Korea. The "oversize" style is characterized by loose clothes and loose tailoring, and is often displayed in exaggerated sizes and contours. The popularity of this style also has a lot to do with young people's pursuit of individuality and comfort.

The popularity of "oversize" style is gradually expanding in China, especially in big cities and fashion circles. Many young people pay more attention to individuality and comfort when choosing clothes, and like loose clothes to show their fashion attitude. At the same time, some fashion brands have begun to launch "oversize" series of clothing to meet market demand.

However, it is worth noting that the popular trend is subjective and changing rapidly, and the popular time will vary according to different regions and groups. Therefore, it is a relative question when "oversize" became popular in China. The popularity of "oversize" style may be different in different time periods and occasions.
