A kimono is a lightweight Japanese robe. You might buy a kimono as a gift for your mom when you travel to Tokyo.
A traditional kimono is nearly floor length, loose-fitting and with very wide sleeves. The cloth belt that ties around the waist of a kimono is called an obi. Both men and women wear kimonos, though they're more frequently worn by women. The word kimono literally means "a thing to wear" or "a thing to put on," from the Japanese roots ki, "wear," and mono, "thing."
