Repacks sample for return with long garment (4)

I believe the answer is:

cape

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

'long garment' is the definition.
'cape' can be an answer for 'garment' (I have seen 'Outer garment' mean 'cape' so perhaps 'garment' could also mean 'cape'). I am unsure of the 'long' bit.

'repacks sample for return with' is the wordplay.
'with' indicates a hidden word.
'for return' says the letters should be written backwards.
'epac' can be found hidden inside 'repacks sample'.
'epac' reversed gives 'CAPE'.

Can you help me to learn more?

(Other definitions for cape that I've seen before include "Shawl" , "Short cloak" , "Batman has one" , "Notorious Chilean headland" , "Cod, for example" .)
