Before you know it, temperatures will start to cool. Shortly after that, they’ll plummet. But, don’t be sad! We merely see this as an opportunity to show off your layering prowess, your collection of outerwear and your finest boots.

You can forget about the heavy wools, the cashmeres and the super-insulated down coats for a few months—now is the time to get your lighter layers in check. Come fall, they’ll keep you warm on crisp mornings and come winter, they’ll keep you toasty when paired with an extra layer on the outside. How could you go wrong?
