I overacted wildly to no real purpose? (10)

I believe the answer is:

decorative

'to no real purpose?' is the definition.

'i overacted wildly' is the wordplay.
'wildly' indicates anagramming the letters.
'i'+'overacted'='ioveracted'
'ioveracted' with letters rearranged gives 'DECORATIVE'.

(Other definitions for decorative that I've seen before include "Ornamental" , "fancy!" .)

I've seen this clue in The Independent.
