What blazers are of a fine, glittery fabric? (6)
I believe the answer is:
aflame
'what blazers are' is the definition.
(something blazing is aflame or on fire)
'a fine glittery fabric?' is the wordplay.
'fine' becomes 'f' (abbreviation).
'glittery fabric?' becomes 'lame' (lame is a type of material).
'a'+'f'+'lame'='AFLAME'
'of' is the link.
(Other definitions for aflame that I've seen before include "Indicating excitement" , "On fire" , "very hot" , "Deeply aroused" , "Ma, flea could be burning" .)
