Morphology

plain + clothes

The meaning 'ordinary clothing' is directly composed from 'plain' (simple, unembellished) + 'clothes' (wearable items), so a B1 learner who knows both words will readily infer the phrase refers to non‑special/ordinary dress. The specific pragmatic use for people who normally wear uniforms (e.g., police 'in plain clothes') is a predictable extension of 'plain' meaning 'not uniform' and thus does not make the expression idiomatic.

Etymology

Plain clothes comes from the idea that someone who usually wears a uniform puts on simple plain clothes so they do not stand out. That's why the term means 'ordinary clothing' worn by police or soldiers 'to blend in'.
