Henry to change pet garment (6-4)

I believe the answer is:

halter-neck

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

'garment' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'henry to change pet' is the wordplay.
'henry' becomes 'H' (symbol for the unit of electrical inductance).
'to change' becomes 'alter' ('alter' can be a synonym of 'change').
'pet' becomes 'neck' (necking is a kind of petting).
'h'+'alter'+'neck'='HALTER-NECK'

Can you help me to learn more?

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