Purpose This thesis aims to increase the success of Korean fashion brands in the Chinese consumer market by providing basic items in fashion colors preferred by women in their twenties and thirties, having the highest purchasing power, in Beijing and Seoul, in the summer of 2012. Research Methodology The street fashion color data were retrieved for the case study by taking pictures and recording videos at the famous fashion streets in Beijing and Seoul. The WINDOWS SPSS 18.0 program was applied, to determine the frequency of street fashion colors. Results The results might be ascribed to the tendency of Chinese women to favor the symbolism of traditional colors. Conversely, women in Seoul have more attachment to international fashion color trends than to the traditional color symbolism. Conclusions This study suggests that Korean companies should consider the differences in street fashion color preferences when planning to launch a fashion brand in the Chinese consumer market. To gain the long-term perspective, further research on the local Chinese area might be essential to help Korean fashion companies and brands launch into the Chinese consumer market.
