The difference between kimono and bathrobe is summarized in Baidu's various answers.

Bathrobe is a kind of portable kimono, and the differences between them are as follows:

1, kimono fabrics are high-grade, while bathrobes are mostly cotton and linen fabrics.

2, kimono wearing method is extremely complicated, bathrobe is a common clothing after soaking in hot springs or bathing. Bathrobe is also common in Japanese summer festivals, celebrations and fireworks shows.

3, kimono is more formal, bathrobe can be casual. Kimono is worn on formal occasions, such as New Year celebrations, adult ceremonies and traditional Japanese weddings. It's time to specify what to wear. Formal kimono is condemned as an unrealistic clothing style because of its heavy wearing, but its advantage is to give the wearer elegant demeanor.

There are many kinds of kimonos. Kimono is divided into men's wear, women's wear, children's wear, single coat and double coat, as well as "wearing" (outer robe) and "wearing" (inner robe) and so on. According to different seasons, kimonos have their own collocation rules in terms of types, materials, patterns and even ornaments, especially those who practice traditional Japanese techniques such as tea ceremony, flower shape and dance, and pay more attention to the tradition of clothing.

Kimono is usually ankle-long, with a cross collar, a right shoulder, wide sleeves, eight legs, no buttons, and a belt with a family emblem printed on it. Bathrobe, as a traditional Japanese summer dress, reflects the coolness of summer as far as possible in color and fancy collocation. Blue background, purple background and white background are the most common, with lovely patterns such as goldfish, fireworks and butterflies.

Bathrobe is a simple kimono, which is cheaper than kimono.
