Glitzy fabric (4)
I believe the answer is:
lame
'glitzy fabric' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lame that I've seen before include "Disabled in leg or foot" , "Rubbish" , "Imperfect - material" , "Unable to walk normally" , "(Of an excuse) unconvincingly feeble" .)
