Independence day, I usually go with your basic color blocking, on account of I don't have any american themed clothing. But comfort for barbequing and watching fireworks is a must, so nothing fancy...super super casual is just how it's always been done where ever I've lived or celebrated the 4th, it's a general rule that the more ridiculous you look, the more patriotic you are lol. You can run with that however you choose, I usually choose to look mildly patriotic. I love this country, but I don't so much love the culture of this country...I love the land, you know? Mildly patriotic.
