Harry’s emblem on front of robe (6)
I believe the answer is:
badger
'harry's' is the definition.
(both can mean to bother or harass)
'emblem on front of robe' is the wordplay.
'emblem' becomes 'badge' (badge is a kind of emblem).
'on front of' says to take the initial letters.
The first letter of 'robe' is 'r'.
'badge'+'r'='BADGER'
(Other definitions for badger that I've seen before include "One tagging" , "ride" , "Carnivore - pester" , "Countryside mammal" , "Member of the weasel family" .)
