The eri or “collar” is the piece of cloth worn around the neck when the kimono is worn. White is the most luxurious color, but there are also red, light purple, yellowish green, birch-colored and deep blue, with the color selection an important point in distinguishing the type of character. Sometimes two eri are worn. They are worn individually like the date-eri on a typical woman’s kimono, and are attached to a fabric base to prevent them from slipping. They are wide at around 15cm in width, and when put on they are folded over 3-4 times with the dōgi worn under the kimono.
