With ultratall boots and superhuman silhouettes storming the runways, fall’s trends embody one unequivocal theme: power. Just in time, Coach has dug into its archives to create the Legacy Collection, whose Rugby Stripe Duffle ($398 at Coach, 595 Madison Ave., at 57th St.; 212-754-0041) was inspired by the brand’s 1973 Duffle Sac. Made from glove-tanned leather and emblazoned with a hand-painted racing stripe, the carryall combines of-the-moment color-blocking with one of Coach’s most iconic shapes. But the biggest selling point for cachet-hungry fashion doyennes? Its lust-inducing limited run of 800.
