From 1978 to 2008, China has gone through 30 years of reform and opening up. After 30 years of vicissitudes, traces of this change can be seen everywhere in the daily life of our people. Thirty years ago, perhaps a brighter dress also represented the decadent ideas of capitalism. At that time, it was still a gray-blue era. For people in their early twenties, owning a shirt is a luxury. Most importantly, this shirt must be "really cool". In the eyes of many people, the spring of China's clothing development and the revival of China's fashion concept began with 1978 when China implemented the reform and opening-up policy. People see bell bottoms, bat shirts, fitness pants and dresses. With the continuous opening-up of China's economy, western culture and fashion from Hong Kong and Taiwan have rapidly entered China, conveying the latest trend information to the younger generation. This change was directly reflected in the 1980s. In 1980s, with the process of reform and opening up and the continuous enrichment of people's material life, great changes have taken place in people's clothing. Bell bottoms are an invincible fashion. Anyone who walks down the street in bell bottoms will have the same effect as streaking now. Fitness pants have been popular for quite a long time. Generally, black is the main color, which is very elastic. Later, the materials of ankle pants became varied, but the basic characteristics remained unchanged: close-fitting, high elasticity and breathability. Jeans are popular for their rough, natural, passionate and energetic style. But for a long time, China people's clothing styles are single, and the colors are basically blue or military green. Jeans split in front of the abdomen, which is considered as "ignoring men and women, reversing right and wrong" and "blindly imitating the western bourgeois lifestyle". Walking down the street in jeans may even encounter "unforgivability". With the liberation of people's minds, tight jeans quickly became the typical clothing of "fashionable youth". With the development of the country and the changes of the times, jeans are widely accepted by all walks of life for their practicality and fashion sense. Nowadays, jeans have become popular in China and become the most common casual wear in wardrobes of men, women and children. Think about clothes that were fashionable in those days, but now they are "out of date", and then look at those young people who go shopping from time to time in boutiques and big shopping malls and buy fashionable clothes. The changes in these 30 years are really earth-shaking.
