New Attire
Sure, the jeans and vest look lends itself well to a brawling style or for use in a one-off Street Fight bout, but for day-to-day competition it looks nothing if not low rent.
As a trio, The Shield looked absolutely awesome in their unique riot squad gear. Since that trio disbanded, Roman Reigns kept hold of The Shield music, attire, and even their entrance for a little while. Where Dean Ambrose is concerned, he made the decision to wrestle in jeans and a vest once The Shield came to an end.
Upon his impending return from injury, a change of attire would give the Lunatic Fringe a fresh feel and hopefully get him away from feeling like the stale act he was for the months prior to his unfortunate injury.
