If I had to boil it down to just one must-have for fall, it would no doubt be a pair of white boots. They'll instantly make your old jeans and blazer combo look hot-off-the-press new and cool, and because they're neutral, they go with pretty much every single thing. Done and done. I am way into these versions by Balenciaga (pictured above), Sam Edelman, Dolce Vita, Loeffler Randall, Alexandre Birman, and Vince.
