Prestige: it follows aristocrat around, mostly (5)
I believe the answer is:
kudos
'prestige' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
(Other definitions for kudos that I've seen before include "'Credit, honour or prestige (5)'" , "Laudation" , "Renown" , "Praise, honour" , "Praise and honours" .)
