I believe the answer is:

khaki

I'm a little stuck... Click here to teach me more about this clue!

'fabric' is the definition.
(khaki is a kind of fabric)

I don't understand how the remainder of the clue works.

(Other definitions for khaki that I've seen before include "Sand-coloured" , "strong fabric" , "Military clothing colour" , "Army fabric" , "Drab military colour" .)

I've seen this clue in The Times.
