Steve is all smiles when he takes the box even if Tony can't see him. If his excitement and happiness were tangible, then Tony would feel it. The clothes aren't really his style, but he doesn't care. They're his size, and they look durable. Denim is super durable. And it's not like he's opposed to wearing tight clothes or anything. He definitely won't be used to the cut of the denim.

He doesn't know how to express thank you without words or writing, so with the items in his hands, he pulls Tony into a brief hug. Merry Christmas, he thinks.
