Totes are ubiquitous among urbanites for a reason: In a mass-transit city, they pick up where cars leave off, holding the day’s essentials from a.m. to p.m. And just like a motor vehicle, a tote offers a variety of ways to express personal style. Anya Hindmarch’s pixelated-patterned version plays off her video-game theme for fall. Jason Wu does a patchwork of multicolored fur — perfect for cold weather. And Ralph Laurenchannels the inner hippie in all of us with its patchwork take, a hodgepodge of fabrics on a leather strap with dangling cords. Whatever the material, these totes are required carrying cases this season.
