Fabric a bit looser, generally? (5)
I believe the answer is:
serge
'fabric' is the definition.
(serge is a kind of fabric)
'a bit looser generally?' is the wordplay.
'a bit' indicates the answer is hidden within the clue (the answer is formed by a bit of the clue).
'SERGE' can be found hidden inside 'looser generally'.
(Other definitions for serge that I've seen before include "Frenchman" , "Twilled fabric; name" , "Stuff" , "Strong twilled worsted fabric" , "Twilled woollen fabric" .)
