How do I solve 9 down in Express Cryptic 20260608?

Question

Accepted Answer

9 down reads "Instruction not to wear so much" (6 letters); the answer is LESSON. It's a charade: the answer breaks into parts in clue order, each part clued by a word or short phrase. No indicators needed; watch for standard abbreviations (RA = artist, US = American, IN = at home) and short synonyms. The full step-by-step breakdown is on this page.
