Komon have an all over repeat pattern and are known as townwear, that is, an everyday wear kimono. Komon kimonos and iro-muji kimonos are becoming more and more rare, as they are not made much anymore; the few kimono makers left now tend to make only very formal, ornate kimonos, which are still worn by some Japanese women on special occasions, and lightweight cotton yukata kimonos, which are often worn to Japanese summer festivals or as house and bath robes. Very few people in Japan wear kimono all the time nowadays, so almost no one buys kimonos such as komon or iro-muji anymore and kimono makers have virtually stopped making them.
