Tony doesn't notice the wariness; he's too busy noticing Steve in that uniform, and... Wait, what is Steve saying?

"No, it-- They did a good job recreating it, it looks like the real thing."

Not that he'd know about it. Really. Maybe. Listen, it's not his fault that his father collected all sorts of crap from World War II, okay?

At Steve's comment, about how not everyone can pull off a suit like him, Tony's lips twitch into an even bigger smirk. Something that looks like a blend between both being impressed and flattered at the comment, even if some part of his brain tries to remind him that it's just a comment. It doesn't mean anything.

Still, whatever. He ignores that nagging little voice down.

"Have you tried any fancy dance moves while I wasn't watching, or are you saving that for later?"
