The World of Suzie Wong

In the 1950s, women in the workforce in Hong Kong started to wear more functional cheongsam made of wool, twill, and other materials. Most were tailor fitted and often came with a matching jacket. The dresses were a fusion of Chinese tradition with modern styles.

Cheongsam were commonly replaced by more comfortable clothing such as sweaters, jeans, business suits and skirts. Due to its restrictive nature, it is now mainly worn as formal wear for important occasions. They are sometimes worn by politicians and film artists in Taiwan and Hong Kong. They are shown in some Chinese movies such as in the 1960s film, The World of Suzie Wong, where actress Nancy Kwan made the cheongsam briefly fashionable in western culture.

However, they are sometimes used as Halloween costumes in some western countries. They are also commonly seen in beauty contests, along with swim suits. Today, cheongsam are only commonly worn day-to-day for some people—restaurant hostesses and serving staff at luxury hotels, for instance—as uniform.
