Yukata are light summer kimono worn by both men and women. Yukata obi are frequently more colourful and may be made of a variety of fabrics. Some men's yukata obi are similar to or the same as kimono obi, while others feature decorative tassels or are made of very wide strips of cotton which are gathered at the ends and are tied loosely around the waist and secured with a bow at the back.

Women often tie yukata obi in various decorative knots, most popularly a large bow. People wearing yukata are a common sight at fireworks displays, bon-odori festivals, and other summer events. The yukata is a casual form of kimono that is also frequently worn after bathing at traditional Japanese inns, Though their use is not limited to after-bath wear, yukata literally means bathing clothes.

A yukata is a cooling garment to wear. Like other forms of clothing based on traditional Japanese garments, it is made with straight seams and wide sleeves. Unlike formal kimono, yukata are typically made of cotton rather than silk or synthetic fabric, and they are unlined.

Traditionally yukata were mostly made of indigo-dyed cotton but today a wide variety of colors and designs is available. Like the more formal kimono, the general rule is the younger the person, the brighter the color and bolder the pattern. A child might wear a multicolored print and a young woman, a floral print, while an older woman would confine herself to a traditional dark blue with geometric patterns. Since the late 1990s, yukata have experienced a bit of a revival, and many young women now wear them in summer in personally distinctive ways not limited by tradition.
