Bruce Banner formal wear tie

[HUMVEE Driver]

Hello RPF, I'm hoping someone can help me out in identifying and locating Bruce Banner's tie from Avengers: Age of Ultron. I've got the suit, but I don't know if I should just bring it to a men's clothing store and ask them or what. Anyway, I can't find a good image of him in his tie, but it looks like it's the same material as his suit. Here he is in his suit: Any help would be appreciated!
Thanks,
Max
