Girls go after celebrated shades (10)
I believe the answer is:
sunglasses
'shades' is the definition.
('sunglasses' can be a synonym of 'shades')
'girls go after celebrated' is the wordplay.
'girls' becomes 'lasses' (lass is a kind of girl**).
'go after' is a charade indicator (letters next to each other).
'celebrated' becomes 'sung' (as opposed to 'unsung').
'lasses' after 'sung' is 'SUNGLASSES'.
(Other definitions for sunglasses that I've seen before include "Shades" , "Tracey Ullman hit" , "viewing aids" , "Fashion accessories" , "They relieve effect of glaring" .)
