Dress warmly before a game of golf in this garment (10)

I believe the answer is:

wraparound

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

'this garment' is the definition.
(wraparound is a kind of garment)

'dress warmly before a game of golf' is the wordplay.
'dress warmly' becomes 'wrap' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'before' says to put letters next to each other.
'game of golf' becomes 'round' (I've seen this before).
'wrap'+'a'+'round'='WRAPAROUND'

'in' acts as a link.

Can you help me to learn more?

(Another definition for wraparound that I've seen is " Hugging".)

I've seen this clue in The Telegraph.
