Glittering range of surplus trousers (8)

I believe the answer is:

lustrous

'glittering' is the definition.
(both can mean shining)

'range of surplus trousers' is the wordplay.
'range of' says the answer is hidden in the clue (a range of letters from the clue).
'LUSTROUS' is hidden within 'surplus trousers'.

(Other definitions for lustrous that I've seen before include "Glossy, shiny" , "Softly glowing" , "Softly bright or glorious as career may be" , "Glowing gently" , "Gleaming" .)

I've seen this clue in The Guardian.
