I'd turn up in a sort of orange fabric (8)
I believe the answer is:
organdie
'fabric' is the definition.
(organdie is a kind of fabric)
'i'd turn up in a sort of orange' is the wordplay.
'turn up' shows that the letters should be reversed in order.
'in' is an insertion indicator.
'a sort of' indicates an anagram.
'id' reversed gives 'di'.
'orange' with letters rearranged gives 'organe'.
'di' inserted into 'organe' is 'ORGANDIE'.
(Other definitions for organdie that I've seen before include "Badly ignored a fine cotton muslin" , "I groaned about translucent fabric" , "Translucent cotton fabric, usually stiffened" , "Orange I'd changed for fine muslin" , "Oddly ignored a fine cotton muslin" .)
