This study compared consumer perceptions of leggings that have changed since the outbreak of Covid-19 with big data analysis. Using Textom, data was collected from Naver and Daum, and the collection period from December 1, 2016 to December 31, 2019 was set to pre-Covid-19 and from January 1, 2020 to April 30, 2021 to post-Covid-19. Based on refined data, frequency analysis, TF-IDF, emotional analysis, semantic network analysis, and CONCOR analysis were conducted. Except for the search term leggings, in frequency analysis ��Andar�� was the highest before Covid-19, while sportswear was the highest after Covid-19, and the TF-IDF showed that ��Andar�� was the highest before Covid-19 and women was the highest after Covid-19. Emotional analysis showed that the rate of positivity was higher than the rate of negativity for both before and after Covid-19, and after Covid-19, the rate of positivity increased even more. According to the CONCOR analysis, pre-Covid-19 was categorized into four groups: Products and Features, Andar, Sweatwear and Mulawear, post-Covid-19 was categorized into three groups: Brand and Utilization and Characteristics, Andar and SNS Impact. Unlike before Covid-19, many brands have appeared, and the use of leggings has also diversified. In addition, the impact of popular celebrities can be seen on SNS, while the impact of brand advertising models has likely decreased.
