Brought back a garment worn by ancient Romans (4)
I believe the answer is:
toga
'garment worn by ancient romans' is the definition.
'toga' can be an answer for 'garment' (I've seen this in another clue). I am not sure about the 'worn by ancient romans' bit.
'brought back a' is the wordplay.
'brought' becomes 'got' ('get' can be a synonym of 'bring').
'back' says the letters should be written backwards.
'got' reversed gives 'tog'.
'tog'+'a'='TOGA'
Can you help me to learn more?
(Other definitions for toga that I've seen before include "Roman dress" , "Graph's y value" , "Got a cloak for an old Roman" , "Got a robe for an old Roman" , "Roman tunic" .)
