A concept: When they first move into the Tower Steve has only ever seen Tony in casual clothes or the Iron Man armor. Then Tony has a board meeting he can’t avoid and he comes to breakfast wearing slacks that do very good things to his ass and a long-sleeved shirt and a fucking vest oh God Steve nearly chokes on his orange juice. Steve didn’t know he liked men in vests until just now but it figured that the most handsome businessman in the world would show him just how much he needed it. Luckily Steve has a good poker face and his face doesn’t betray how much he wants to peel Tony out of his vest and slacks.

So Tony just sees a blank-faced Steve pour his orange juice down his front. He stares at Steve, pondering what to say, before deciding not to say anything because what the fuck and turning and leaving with his travel mug of coffee.
