Re: Update the outfit for next solo film
I dont think an explanation with the suit is even needed. I think the audience would accept a different costume in the same way that they assume Iron Man will have new armor for every movie - just as IM upgrades his armor, Cap is constantly being provided with upgraded costumes/outfits which are improvements on each of their predecessors but may change a bit stylistically.
How many more times? James Bond is not a ****ing codename.
