Kimono (Japanese: 着物, literally "something worn", i.e., "clothes") are the traditional garments of Japan. Originally the word kimono was used for all types of clothing, but it came to refer specifically to the full-length garment that is still worn by women, men, and children.

Kimono are T-shaped, straight-lined robes that fall to the ankle, with collars and full-length sleeves. The sleeves are commonly very wide at the wrist, perhaps a half meter. Traditionally, unmarried women wear kimono with extremely long sleeves that extend almost to the floor. The robe is wrapped around the body, always with the left side over the right, and secured by a wide belt tied in the back, called an obi.

HISTORY

The modern kimono began to take shape in the Heian period (CE 794–1192). Since then the basic shape of both men's and women's kimono has remained essentially unchanged.

Traditionally, all women's kimono were basically one size. Tucks and folds in the fabric accommodated different body heights and shapes. Kimono were made from a single bolt of kimono fabric. The bolts came in standard dimensions, and all the fabric was used in the making of the kimono. All traditional kimono are sewn by hand, and the fabrics from which they are created are also frequently hand made and hand decorated. Various techniques such as yuzen dye resist (made with a rice paste), shibori, as well as hand-painting are incorporated into the kimono which governs where the pattern is distributed and if it is a singular or a repeating pattern. Repeating patterns that cover a large section of the kimono are traditionally done with the yuzen resist technique and a stencil.

In the past, a kimono would often be entirely taken apart for washing, and then re-sewn for wearing. Modern fabrics and cleaning methods have largely eliminated this practice. "Basting stitches"—long, loose stitches—are sometimes placed around the outside edges of the kimono for storage. They help to prevent bunching, folding and wrinkling, and keep the kimono's layers in alignment.

Over time there have been many variations in colour, fabric and style, as well as accessories such as the obi.

There are styles of kimono for various occasions, ranging from extremely formal to very casual. The level of formality of women's kimono is determined by the shape (mostly the length of the sleeves), pattern and fabric, and also the colour. Men's kimono are usually one basic shape and are mainly worn in subdued colours. Formality is determined by the type and colour of accessories, the fabric, and the number or absence of mon (family crests). Silk is the most desirable, and most formal, fabric. Cotton is more casual. These days there are polyester kimono as well; they are generally more casual.

Today, both men's and women's kimono are increasingly available in different sizes. With the tradition of kimono being made from a single bolt of cloth, larger sizes are difficult to find and very expensive to have made. Very tall or heavy people, such as sumo wrestlers, have kimono custom-made.Kimono can be expensive. A woman's kimono may easily exceed US$10,000; a complete kimono outfit, with kimono, undergarments, obi, ties, socks, sandals and accessories, can exceed US$20,000. A single obi may cost several thousand dollars. In practice, however, most kimono owned by typical kimono hobbyists or by practitioners of traditional arts are far less expensive. Enterprising people make their own kimono and undergarments since they follow a standard pattern, or they "recycle" older kimono. Cheaper and machine-made fabrics substitute for the traditional hand-dyed silk. There is also a thriving business in second-hand kimono in Japan. Women's obi, however, remain an expensive item. Even second hand ones can cost hundreds of dollars, and they are difficult for inexperienced people to make. Men's obi, even those made from silk, tend to be much cheaper, because they are narrower and shorter than those worn by women.

Kimono are never wasted. Old kimono are recycled in various ways: they may be altered to make haori or to make kimono for children; the fabric may be used to patch similar kimono; larger parts of fabric are used for making kimono accessories such as handbags; smaller parts can be used to make covers, bags or cases for various implements, especially things like the sweet-picks used in tea ceremony. Kimono that are damaged in the lower portions can also be worn under hakama to hide the damage.

Today, kimono are usually worn only on special occasions, and mostly by women. A few older women and even fewer men still wear kimono on a daily basis. Men wear kimono most often at weddings and at the tea ceremony. Kimono are also worn by both men and women in certain sports, such as kendo. Professional sumo wrestlers are required to wear kimono whenever they appear in public outside of the ring.

There is a large number of kimono hobbyists in Japan, where it is possible to take courses on wearing kimono. The classes cover selecting seasonally and event-appropriate patterns and fabrics, matching the kimono undergarments and accessories to the kimono, selecting and tying an obi, and other topics. There are also clubs devoted to kimono culture, such as Kimono de Ginza.

KIMONO ACCESSORIES AND GARMENTS

• Geta (下駄). Geta are wooden sandals worn by men and women with yukata. A slightly different style of geta is worn by geisha.
• Hakama (袴): a divided or undivided skirt, rather like a very wide pair of pants, traditionally worn only by men but now worn also by women, and also worn in certain martial arts such as aikido. A hakama typically has pleats, a koshiita - a stiff or padded part in the lower back of the wearer, and himo - long lengths of fabric that are tied around the waist around an obi (described below). Hakama are worn in several budo arts such as aikido, kendo, iaido and naginata. They can range from very formal to visiting wear, depending on pattern. While very formal women's outfits do not include hakama, men's usually do.
• Haori (羽織): Hip- or thigh-length kimono coat which adds formality. Haori were originally reserved for men, until fashions changed at the end of the Meiji period. They are now worn by both men and women, though women's kimono jackets tend to be longer.
• Haori-himo (羽織紐): a tasseled, woven string fastener for the haori. The most formal colour is white.
• Jūnihitoe (十二単): twelve-layered-robe, worn in old times by women at court. Today only worn during most formal occasions at court (imperial weddings, enthronement ceremony, etc.) or can be seen in museums.
• Kanzashi (簪): Hair ornaments worn in the coiffured hair style which often accompanies kimono. These may take the form of silk flowers, wooden combs, jade hairpins etc..
• Obi (帯): The Japanese equivalent of a sash or belt, which is used for a kimono or yukata. Obi are generally worn differently depending on the occasion, and they are usually more intricate for women.
• Tabi (足袋): Ankle high, divided-toe socks that are usually worn with sandals. They also come in a boot form.
• Waraji (草鞋): Straw rope sandals. Most often seen on monks.
• Zōri (草履): Cloth, leather or grass-woven sandals. Zori may be highly decorated with intricate stitching or with no decoration at all. They are worn by both men and women. Grass woven zori with white straps are the most formal for men. They are similar in design to flip-flops.
