Examples include top blokes wearing glasses (9)
I believe the answer is:
specimens
'examples' is the definition.
(I know this)
'include top blokes wearing glasses' is the wordplay.
'top' says to take the initial letters (in a down clue, the first letter is top).
'blokes' becomes 'men' (bloke can informally mean a man).
'wearing' indicates putting letters inside.
'glasses' becomes 'specs' (spectacles).
The first letter of 'include' is 'i'.
'i'+'men'='imen'
'imen' put within 'specs' is 'SPECIMENS'.
(Other definitions for specimens that I've seen before include "Samples of Pisces men" , "Representative samples" , "Pisces men make prime examples" .)
