If someone looks dishevelled, their hair, clothes, or whole appearance is very untidy — as if they just got out of bed, ran through wind, or stopped fussing for a moment. The mess is about things being out of place, not necessarily dirty. A clean person can still look dishevelled. British spelling likes two l's (dishevelled); American writing usually uses one (disheveled). It is a little more bookish than messy or scruffy, though newspapers use it all the time for people stepping off planes. Though actually, the oldest picture inside the word is hair: it comes from French for with the hair undone. English later stretched it to shirts, coats, and a whole look. Teenagers more often say messy; this word still sounds a bit like a grown-up noticing.

衣冠不整的；頭髮蓬亂的（凌亂，不一定是髒）
