Since the timeline is only a year (so far) and they've shown the characters raiding department stores, their clothes should reflect readily available, common clothing.
Instead, Rick wears a holster that hasn't been in service for nearly forty years, the Gov has a $900 designer hunting vest, and I won't even bother discussing Michonee's leathery outfit. :lol
It just feels like the costumer went out of their way to create these unique looks and its at a point that's a bit unbelievable ... To me at least.
The holster goes with the firearm, which hasn't been made in as many years. A revolver is less common with law now, most carry semiauto handguns, so an old holster makes sense.
The governor is a corrupt character who turned himself into a leader. So expensive attire makes sense for him.
