Something one can assume to vary in cut (5)
I believe the answer is:
tunic
'something one can assume' is the definition.
I can't judge whether this defines the answer.
'vary in cut' is the wordplay.
'vary' indicates an anagram.
'in'+'cut'='incut'
'incut' is an anagram of 'TUNIC'.
'to' is the link.
Can you help me to learn more?
(Other definitions for tunic that I've seen before include "Cut in (anag)" , "Smock" , "Close fitting jacket as part of uniform" , "Simple garment" , "(Policeman's) jacket" .)
