Look at ship delivering cosmetic (8)
I believe the answer is:
eyeliner
'cosmetic' is the definition.
(I know that eyeliner is a type of make-up)
'look at ship' is the wordplay.
'look' becomes 'eye' (eyeing is a kind of looking).
'at' means one lot of letters go next to another.
'ship' becomes 'liner' (as in an ocean liner).
'eye'+'liner'='EYELINER'
'delivering' is the link.
(Other definitions for eyeliner that I've seen before include "Type of make-up" , "Dark marks left by this" , "Makeup for the peepers" , "highlight for look-out" , "Cosmetic pencil" .)
