When Sylvie comes to the door, Bucky is too busy staring at her face to even realize what she's wearing until she draws attention to it. His gaze sweeps down the length of her and she looks casual but well put together, and it most likely wouldn't be a problem. Bucky is more concerned that he massively misrepresented his intentions.

"Hi," he says back to her, chuckling a little and leaning in to press a quick kiss to her cheek. "You don't have to. The place we're going doesn't have a dress code but it does have cloth napkins."

He smiles widely at her and then lets out another soft laugh, amused by the whole thing. "Sorry, I should have been more clear."
