I believe the answer is:

retrograde

'moving backwards' is the definition.
(I've seen this before)

'from the past to a degree' is the wordplay.
'from the past' becomes 'retro' (I've seen this in another clue).
'to a degree' becomes 'grade' (synonyms).
'retro'+'grade'='RETROGRADE'

'imitating style' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
