Self-righteous tailors randomly caught by microphone (10)

Ross

I believe the answer is:

moralistic

I'm a little stuck... Click here to teach me more about this clue!

'self-righteous' is the definition.
Both the answer and definition are adjectives. Perhaps there's an association between them I don't understand?

'tailors randomly caught by microphone' is the wordplay.
'randomly' is an anagram indicator (I've seen 'roaming randomly' mean this).
'caught by' indicates putting letters inside.
'microphone' becomes 'mic'.
'tailors' is an anagram of 'oralist'.
'oralist' placed inside 'mic' is 'MORALISTIC'.

Can you help me to learn more?

(Other definitions for moralistic that I've seen before include "Pronouncing on issues of right and wrong" , "Preachy" .)
