Move along, food trucks: mobile boutiques are hitting the streets. Styleliner (pictured)—an old potato-chip delivery truck—peddles Spanish crystal-and-mesh clutches and other global finds up and down the East Coast. Portland, Oregon, is naturally hip to the craze: Lodekka, a 1965 double-decker, carries a wide range—from 1970’s patterned dresses to tweed coats. Dallas’s bright green Vintagemobile also specializes in retro. You’ll find paisley tops, YSL sunglasses, and cowboy boots from the 50’s. And in St. Paul, Minnesota, Uniquely Attainable has gone the housewares route: Midcentury Modern furniture and kitschy pillows are sold from a school bus.
