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.
However, most kimonos owned by kimono hobbyists or by practitioners of traditional arts are far less expensive.
Enterprising people make their own kimono and undergarments by following a standard pattern, or by recycling older kimonos.

Cheaper and machine-made fabrics can substitute for the traditional hand-dyed silk.
There is also a thriving business in Japan for second-hand kimonos, which can cost as little as ￥500 (about $5). Women's obis, however, mostly remain an expensive item.
Although simple patterned or plain colored ones can cost as little as ￥1,500 (about $15), even a used obi can cost hundreds of dollars, and experienced craftsmanship is required to make them.
Men's obis, even those made from silk, tend to be much less expensive, because they are narrower, shorter and less decorative than those worn by women.
