Rule wearies members who go around in casual clothing (11)

I believe the answer is:

leisurewear

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

'go around in casual clothing' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'rule wearies members' is the wordplay.
'members' is an anagram indicator (members or parts of the anagram in a different way).
'rule'+'wearies'='rulewearies'
'rulewearies' is an anagram of 'LEISUREWEAR'.

'who' is the link.

Can you help me to learn more?

(Another definition for leisurewear that I've seen is " tracksuits and the like".)

I've seen this clue in The Irish Times.
