This study is a review of the clothing behavior of kidult group that is a new minority group in 21st century. Kidult is the compound word of kid and adult and refers the persons who have become adults but with the inclination to focus on childlike culture and consumption. As the background of the appearance of the kidult group these days, the prevalence of throwback fashions, high valuation of appearance, the phenomenon to prefer light things caused by economic depression, the individualism that does not care about others and the ageless phenomenon that the consumptions are mind age oriented, may be pointed out. The most prominent cloth behavioral characters of the kidult group are that they enjoy bounding color combinations such as candy color and. that cute t-shirts, crop pants and volume skirts of girlish look are easily found. Also, they enjoy toy-like ornaments and illustrated clothes or accessories and the school uniform fashion implying nostalgia for girl-hood and lovely make-up indicate the kidult inclination.
