Steve's eyebrows rise skeptically for a second, wondering how Tony would know what his original uniform looked like, until he remembers that okay, yeah, Howard had seen it and probably had pictures, both of the moving and non-moving variety. And there's a whole Smithsonian exhibit dedicated to his time in WWII. Steve himself still has his old uniform displayed on a mannequin back home.

Okay, he realizes, it's not that surprising.

When Tony's smirk gets bigger, like Steve’s finally said something right for a change, he can't keep himself from grinning. Finally.

You didn't stay long enough to teach me any fancy ones is the first thing he wants to say, but Steve thinks better of it before it's too late. He's still sober after all. Soldiers can't drink on the job.

"Ahhhhh ... no. Not yet." In the middle of that sentence he glances down briefly, like he's embarrassed to admit it. Especially since Tony took the time to actually teach him.

"If I dance now, no one will have a reason to bid on the auction later," he teases, because Steve isn't ready to talk about the real reason why he's yet to step foot on the dance floor. But Tony can probably guess the real reason himself, given how nervous Steve was yesterday, and the news about Peggy that came out since then.

"You seem right in your element though. Enjoying yourself?"
