Olive ordered dainty fabric (5)
I believe the answer is:
voile
'dainty fabric' is the definition.
'voile' can be an answer for 'fabric' (voile is a kind of fabric). I'm unsure of the 'dainty' bit.
'olive ordered' is the wordplay.
'ordered' is an anagram indicator.
'olive' with letters rearranged gives 'VOILE'.
Can you help me to learn more?
(Other definitions for voile that I've seen before include "Light semi-transparent fabric" , "fine material" , "Sheer fabric" .)
