more than a little flustered (and whose fault is that?)

Sam lands on one knee before rising slowly, and it feels like someone’s placed a vacuum directly into Bucky’s lungs. He’d known that Wakandan tech was sleek. Obviously, the material of Sam’s old suit had been bulkier, thick enough to be practical against all manner of knives and bullets, but unwieldy and certainly not form-fitting. The new suit, though, clings to Sam’s body in a way that accentuates the contours and curves and muscles of his torso and chest that Bucky had known were hidden under the looser clothing Sam usually preferred. It's just that seeing it all on display is a little more overwhelming than he'd expected.Or: Bucky sees Sam in the new suit for the first time. To say he’s flustered would be an understatement.
