Vintage 501 jeans, army duffel bag, white v-neck hanes shirt, leather jacket, chippiwa engineer boots and newsboy cap in winter/fall. Brando in The Wild Ones vibe.
Dickies, chuck taylors (or vans), wifebeater in warm weather. So cal stuff.
It's important to me, when I travel the states, to wear and use classic American brands on the trip. People recognize it, and respect that.
That's just me though.
