Pack some garments to wear (4)
I believe the answer is:
stow
'pack' is the definition.
(I know that stow is a more specific form of the action pack)
'some garments to wear' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'STOW' is hidden in the letters of 'garments to wear'.
(Other definitions for stow that I've seen before include "Pack, put away" , "Store away tidily" , "Put tidily away" , "Deposit" , "Place in storage receptacle" .)
