I still think the right "items" are important though. God is in the details. That Patriotic Backyard Dad BBQ fit would look better to me if he had slimmer chinos (RRL officer or UNIS or something) and Sperry CVO or Vans. Little things like rolling sleeves up past elbow, not unbuttoning 3 buttons, are simple but subtle difference that make or break an outfit. Just like collar roll, tie dimple, break, etc.
