Trim and graceful (5)
I believe the answer is:
sleek
'trim and graceful' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sleek that I've seen before include "(Of hair) smooth, glossy" , "with glossy coats" , "Excessively well-groomed" , "Pleasingly smooth" , "Looking prosperous" .)
