Evocative of the past (5)
I believe the answer is:
retro
'evocative of the past' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for retro that I've seen before include "Imitating a style from the recent past" , "Describes the style of an earlier time, in short" , "In a backward-looking style" , "Reliving the past" , "Slangy adjective for harking back to the past" .)
