Worker by sea with personal clothing (4-2-4)
I believe the answer is:
hand-me-down
'clothing' is the definition.
(hand-me-down is a kind of clothing)
'worker by sea with personal' is the wordplay.
'worker' becomes 'hand' (hand is a kind of worker).
'by' means one lot of letters go next to another.
'sea' becomes 'med' (short for Mediterranean).
'with' says to put letters next to each other.
'personal' becomes 'own' (eg one's own possessions are personal possessions).
'hand'+'med'+'own'='HAND-ME-DOWN'
(Other definitions for hand-me-down that I've seen before include "Passed-on clothing" , "Item passed on" , "Garment passed on to another" , "Second-hand garment" .)
