New gear after work, girls? Aida may look better with these on (5,7)
I believe the answer is:
opera glasses
'aida may look better with these on' is the definition.
(Aida is an opera)
'new gear after work girls?' is the wordplay.
'new' is an anagram indicator.
'after' is a charade indicator (letters next to each other).
'work' becomes 'op' (abbreviation for opus).
'girls?' becomes 'lasses' (lass can informally mean a girl).
'gear' with letters rearranged gives 'erag'.
'erag' after 'op' is 'operag'.
'operag'+'lasses'='OPERA-GLASSES'
(Other definitions for opera glasses that I've seen before include "Small binoculars for use at the theatre" , "visual aid" , "visual aids" , "Theatre viewing aid" , "you could see through them" .)
