Kimono History and Information

Kimono originally derived from the garments worn in China.
Japanese kimono was invented in the Heian period (794-1192). Straight cuts of fabric were sewn together to create a garment that fit every type of body shape. It was easy to wear and adaptable.
Kimonos have evolved greatly in terms of design, fabric and wearability.
Traditional kimono is hard to wear and is very expensive. Newer kimono have been created using linen, rayon and polyester to reduce cost, cater to all seasons and to improve mobility. (Sources from Kyoto Inn&Tour)

Kimono are wrapped around the body, always with the left side over the right (except when dressing the dead for burial) and secured by a sash called an obi, which is tied at the back. Kimono are generally worn with traditional footwear (zōri or geta) and split-toe socks (tabi).

Types of kimono:

(振袖): furisode literally translates as swinging sleeves—the sleeves of furisode average between 39 and 42 inches (110 cm) in length. Furisode are the most formal kimono for unmarried women, with colorful patterns that cover the entire garment. They are usually worn at coming-of-age ceremonies (seijin shiki), graduation ceremonies and by unmarried female relatives of the bride at weddings.

(訪問着): literally translates as visiting wear. Characterized by patterns that flow over the shoulders, seams and sleeves, hōmongi rank slightly higher than their close relative, the tsukesage. Hōmongi may be worn by both married and unmarried women; often friends of the bride will wear hōmongi at weddings (except relatives) and receptions. They may also be worn to formal parties.

(付け下げ): has more modest patterns that cover a smaller area—mainly below the waist—than the more formal hōmongi. They may also be worn by married women.The differences from homongi is the size of the pattern, seam connection, and not same clothes at inside and outside at "hakke." General tsukesage is often used for parties, not ceremonies.

(色無地): single-colored kimono that may be worn by married and unmarried women. They are mainly worn to tea ceremonies. The dyed silk may be figured (rinzu, similar to jacquard), but has no differently colored patterns. It comes from the word "muji" which means plain or solid and "iro" which means color.

(小紋): "fine pattern". Kimono with a small, repeated pattern throughout the garment. This style is more casual and may be worn around town, or dressed up with a formal obi for a restaurant. Both married and unmarried women may wear komon.

Edo komon
(江戸小紋): is a type of komon characterized by tiny dots arranged in dense patterns that form larger designs. A kimono with this type of pattern is of the same formality as an iromuji, and when decorated with kamon, may be worn as visiting wear (equivalent to a tsukesage or hōmongi).

(色留袖): single-color kimono, patterned only below the waistline. Irotomesode with five family crests are as formal as kurotomesode, and are worn by married and unmarried women, usually close relatives of the bride and groom at weddings and a medal ceremony at the royal court. An irotomesode may have three or one kamon=family crests. Those are used as a semi-formal kimono at a party and conferment.

(黒留袖): a black kimono patterned only below the waistline, kuro-tomesode is the most formal kimono for married women. They are often worn by the mothers of the bride and groom at weddings. Kuro-tomesode usually have five kamon=royal crests, printed on the sleeves, chest and back of the kimono.

Uchikake (打掛) is a highly formal kimono worn only by a bride or at a stage performance. The Uchikake is often heavily brocaded and is supposed to be worn outside the actual kimono and obi, as a coat.  It is supposed to trail along the floor, this is also why it is heavily padded along the hem. The uchikake of the bridal costume is either white or very colorful.

Men's Kimono/Yukata

In contrast to women's kimono, men's kimono outfits are far simpler, typically consisting of five pieces, not including footwear.
Men's kimono sleeves are attached to the body of the kimono with no more than a few inches unattached at the bottom.

The typical men's kimono is a subdued, dark color. Fabrics are usually matte.
