Fixes bunk to please executive outfit (9,4)

I believe the answer is:

pinstripe suit

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

'executive outfit' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'fixes bunk to please' is the wordplay.
'fixes' becomes 'pins' (pinning is a kind of fixing).
'bunk' becomes 'tripe' (I've seen this before).
'to please' becomes 'suit' (I've seen this in another clue).
'pins'+'tripe'+'suit'='PINSTRIPE SUIT'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
