New pictures from location shooting are surfacing... Variations are appearing. He's wearing a black shirt for this outing. And it looks dapper indeed - the navy on black is muted in this lighting.
Minor spoilers in the photos, I guess.
I'm getting used to seeing a guy with a top button one up without a tie. Actually saw a guy on the street wearing his shirt this way yesterday. I grew up thinking you'd only do this with a tie, so it's still a bit jarring.
