Collars, hats, and sleeves can help you make bold fashion statements. These essays show how the Japanese have accomplished that with both traditional clothing and Western styles. Figurative takes on these four kanji astonish even more. Collars are associated with heart-to-heart talks. Hats help you say that you admire someone. The foot of a mountain is figuratively its hem. As such, 裾 can represent "extent of something" and "outskirts," even symbolizing the edge of a coral reef. And sleeves are connected with leaders, passivity, coldness to people, and destiny, plus the wings of buildings, stages, and desks.
