What Are Idioms for Fashion?

A phrase counts when its clothes words point to style, dress, or how a person looks. A few entries, such as “not a good fit” and “trendsetter”, are common collocations rather than strict idioms, and the guide says so. Eight phrases only borrow a clothes word for money, effort, or feelings, and they sit in their own section. Other look-alike phrases are not idioms at all, and that section names them too.
