Don't let Steve pick his own clothes, Clint. He has no sense of fashion. The only reason he's dressed as well as he is now is because Verity picked out his clothes for him, to match his godawful red, white, and blue hat.

Unsurprisingly, the 'boys' section will have the best fits for coats. Also unsurprisingly, there are very few there that are formal and as old man-esque as what Steve walked into this world wearing. Some of them are downright silly. There's a Hulk coat over there. No, the Hawkeye coat is not in the discount rack. Fear not for your feels, Clint.

"They're all so..colorful?" Steve seems completely oblivious that these are clearly children's clothes. He's pulling on a boring black coat and then taking it off again. "I guess that's more common in the future." Clint's wearing purple, this only reinforces Steve's misconceptions.
