Getting to be attractive (8)
I believe the answer is:
fetching
This clue is a double definition.
'getting' is the first definition.
('fetch' can be a synonym of 'get')
'attractive' is the second definition.
('fetching' can be similar in meaning to 'attractive')
'to be' acts as a link.
(Other definitions for fetching that I've seen before include "a delight" , "Attractive; bringing" , "collection" , "charming" , "Getting" .)
