Along with every era and culture, Japan formed its own sense of fashion in the feudal era. Japan specialized with silk, this silk was used to create some of the most beautiful pieces of tapestry and clothes known to the world. One of the most popular of these master pieces were the kimonos. Kimonos served as a unisex robe or dress. They were extremely elaborate, even in the way you put them on. Kimonos had several ties which had to be put together in order for them to stay together. the designs of kimonos ranged from basic to elaborate depending on the social class of the wearer. Older samurai would wear dark shades of grays and blacks in order to represent their age and show modesty, while children would wear an array of several colors to represent their springing youth. The popularity of kimonos grew as summer days grew hotter in Japan, and the famous Japanese silk provided a comfortable coolness in the heat. Japanese fashion focused on the natural beauty of nature, and tried to incorporate it into the clothes. Head pieces were donned by women of high status, these head pieces were often butterflies or eccentric hair sticks meant to hold the lengthy hair that women had. When it came to hair, men often had basic hair styles or sported ponytails and loose buns. Once men grew old they would grow it out in order to represent the wisdom they have earned through life.
