What is business casual, really? In Silicon Valley it's literally pajamas. In Denver, probably a vintage plaid and a Patagonia jacket. To me, business casual is basically jeans with a blazer thrown on. This outfit hits the sweet spot, denim on denim with a blazer and vintage pumps. Of course, when you work from home like me, this is considered the height of formal style. Basically the usual uniform is no pants.
