10Poe has a more active role
In The Last Jedi, Poe Dameron was given a larger role than the one he'd had in The Force Awakens; but when all was said and done, it was hard to find anything meaningful or enjoyable about his role as the self-interested
troublemaker in the second film of the sequel trilogy. Poe's actions led the Resistance into more trouble than they would have been otherwise, and he seldom set foot in any real conflict.
However, if these new costumes are to be believed, viewers will get to witness "Adventure Poe," now dressed in traditional rebel casual attire, as well as a scarf, a holster belt, and what appears to be a bandoleer.
