What are the different design trends in each era after the 20th century?

The 1930s was the most gorgeous and prosperous period of women's wear in Shanghai. As the main popular women's dress, cheongsam has replaced tops and skirts as the most commonly used fashion. Its style changes a lot, and the collar, sleeves and lapels show different appearance styles with the change of cycloid. They attach great importance to the description of details and are exquisite in texture and workmanship. Western-style clothing users are mostly European fashionable women, but this form is not the mainstream of fashion. After the Anti-Japanese War in Songhu, women's fashion tends to be simple. In the 1940s, during the period of War of Resistance against Japanese Aggression, most citizens' clothes became simple, and even the wealthy class had no intention of extravagant makeup because of the atmosphere of war. After the victory of the Anti-Japanese War, the popularity of women's clothing flourished again. Western-style clothing, especially American fashion, has a certain market among fashionable women, and the number of wearers who completely adopt western-style structure is increasing day by day. From the 1930s, there were fashionable women wearing men's suits and trousers in Shanghai, and fashionable women wearing men's jackets in the late 1940s. Western-style coats have always been very popular. During this period, textiles imported from Europe and America, such as British flannel, herringbone, women's tweed, plaid woolen fabrics and American "cloth" (plain cloth), were very popular and played a role in demonstrating and guiding domestic fabrics. The widespread use of textile printing and dyeing machinery, the introduction of new chemical dyes and the influence of western art schools on patterns have made domestic textiles take on a new look: new silk varieties such as antique satin and brocade are often used in popular women's wear; Satin, silk, crepe and velvet are widely used; Calico has a wider spectrum and is widely used in fashion; Monochrome fabrics account for an increasing proportion, such as the cloth once widely used in cheongsam (a blue cotton cloth dyed with chemical dyes); Domestic woolen cloth is also a common fabric for fashionable women's wear, and its appearance is almost the same as that imported from Europe.
