Green fabric? (4)

I believe the answer is:

lawn

I believe this clue is a double definition.

'green' is the first definition.
(thesaurus)

'fabric?' is the second definition.
(thesaurus)

(Other definitions for lawn that I've seen before include "Grass-covered ground" , "Patch of grass in the garden" , "sleeves composer?" , "Type of thin linen or cotton" , "Fine fabric" .)

I've seen this clue in the Evening Standard.
