We all remember the Electric Smurf Costumeof the 90's and the change he had whn Pre Flashpoint Supes ened up in the New 52 universe by wearing firstly a black, capeless suit and then wearing an all blue costume during the Rebirth version, then a new post Reborn costume before returning to his classic look for Action no1000 (all though I do believe it is a revised version of the suit).
But would you be in favour for a new costume if they would announce it in terms of shaking the Status Quo a bit?
