It doesn't even have to be 'all over', just anything? Becuase so far it's been nothing; which is weird since they made the effort to include him in the Comic Con trailer.
It took six years to get here, but I'm glad there's finally a cowl that matches the rest of the Flash costume. (And again, I can't believe they let him wear that other thing for a whole season.) Some of the tweaks make a world of difference. I doubt it, but I wonder if they'll mention the suit update in the narrative?
