Strictly practical restyled Roman tunic (10)
I believe the answer is:
unromantic
'strictly practical' is the definition.
'unromantic' can be an answer for 'practical' (thesaurus). I am unsure of the 'strictly' bit.
'restyled roman tunic' is the wordplay.
'restyled' is an anagram indicator.
'roman'+'tunic'='romantunic'
'romantunic' anagrammed gives 'UNROMANTIC'.
Can you help me to learn more?
(Other definitions for unromantic that I've seen before include "Hard-headed" , "without affection?" , "Not loving or amorous" , "As classical music may be narrowly called" , "displaying no outward affection" .)
