Reportedly, rustic steps in vogue (5)
I believe the answer is:
style
'vogue' is the definition.
(I know that vogue can be written as style)
'reportedly rustic steps' is the wordplay.
'reportedly' indicates a 'sounds like' (homophone) clue.
'rustic steps' becomes 'stile' (rural gate containing a set of steps).
'stile' is a homophone of 'STYLE'.
'in' is the link.
(Other definitions for style that I've seen before include "Chic" , "Pointed pen" , "Vogue or grace" , "Characteristic manner" , "Official title; manner" .)
