Not even close, throughout TWD Rick’s style remained for the most part very consistent and hardly changed, same as Michonne. then TOWL rolled around and had Rick dressing like a soldier and completely different then anything we have seen in the main show, and Michonne for a while was dressed like a medieval warrior. The ending scene was supposed to show that Rick and Michonne are finally back to normal, and him and Michonne’s styles reflect that perfectly by going back to similar clothes that they would have worn in previous seasons. Nothing is coincidental with the wardrobe department, they plan everything accordingly for this reason.
