A light summer kimono, often worn to festivals and other special occasions. In other seasons, it is typically worn after a bath in a hot spring resort.
All colors and styles of yukata are aliased to their kimono variant.
How to tell if it's a yukata.
Yukata can be distinguished from kimono by looking for an interior lining, which yukata never has, its made from one singular fabric.¹
Look at the neckline too, if there is an underlayer, typically white, that is the juban. Yukata does not require juban to be worn underneath.² Juban can still be worn with yukata, but it should never be visible, which it is with kimono.¹ if you can see the layer underneath the collar, it is not a yukata, at least in presentation.
The obi can also help to distinguish kimono from yukata. Yukata is worn with a thinner hanhaba obi, while kimono is typically worn with a formal silk obi, more elaborate in style and accessories. Kimono is sometimes worn with hanhaba obi, but it is out of the ordinary to wear yukata with an elaborate formal obi.¹
