Removing these, does fat lady appear smaller? (5,7)
I believe the answer is:
opera glasses
'appear smaller?' is the definition.
I can't tell whether this definition defines the answer.
'removing these does fat lady' is the wordplay.
I cannot really see how this works, but
'lady' could be 'ag' and 'ag' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for opera glasses that I've seen before include "Theatre viewing aid" , "visual aids" , "Theatre viewers" , "Small binoculars for use at the theatre" , "visual aid" .)
