Bright; well-dressed (5)
I believe the answer is:
smart
I believe this clue is a double definition.
'bright' is the first definition.
(synonyms)
'well-dressed' is the second definition.
(I've seen this before)
(Other definitions for smart that I've seen before include "well-kept" , "Brainy" , "Quick - trim" , "Clean, tidy; clever" , "Clean and stylish" .)
