Fine fabric needs about inch off (7)
I believe the answer is:
chiffon
'fine fabric' is the definition.
'chiffon' can be an answer for 'fabric' (chiffon is a kind of fabric). I am not sure about the 'fine' bit.
'about inch off' is the wordplay.
'about' indicates anagramming the letters.
'inch'+'off'='inchoff'
'inchoff' anagrammed gives 'CHIFFON'.
'needs' is the link.
Can you help me to learn more?
(Other definitions for chiffon that I've seen before include "Fine material" , "Sheer silk or rayon fabric" , "Fine, near-transparent fabric" , "Thin light fabric" , "dress material" .)
