Spruce, dapper (5)
I believe the answer is:
natty
This clue is a double definition.
'spruce' is the first definition.
(I know that spruce can be written as natty)
'dapper' is the second definition.
(I know that dapper can be written as natty)
(Other definitions for natty that I've seen before include "Smart, fashionable (colloq.)" , "Smartly dressed" , "Smart, spruce" , "Dapper (colloq.)" , "Flashily smart" .)
