Big and beautiful! (8)
I believe the answer is:
handsome
This clue is a double definition.
'big' is the first definition.
('handsome' can be a synonym of 'big')
'beautiful' is the second definition.
('handsome' can be similar in meaning to 'beautiful')
'and' acts as a link.
(Other definitions for handsome that I've seen before include "Attractive, liberal" , "Well-proportioned" , "Striking" , "Fit" , "Good-looking, as a male say" .)
