Nattily dressed (6)
I believe the answer is:
dapper
'nattily dressed' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dapper that I've seen before include "Neat and well dressed" , "Smart; jaunty" , "Neatly turned out" , "Neat and stylishly dressed" , "Quick" .)
