Trim, neat (9)
I believe the answer is:
shipshape
This clue is a double definition.
'trim' is the first definition.
(I know that trim can be written as shipshape)
'neat' is the second definition.

(Other definitions for shipshape that I've seen before include "Hash pipes may be in good order - like sailor?" , "Neat and trim" , "In good order, like well-dressed sailor?" , "fashionable in Bristol" , "In seaworthy condition" .)
