Even if you’re currently experiencing hot weather, there are moments when having a light layer on hand or in your closet is an absolute must. Even though I tend to run hot, I like having a light cardigan, jacket, or button-down shirt near my person at all times.
A lightweight layer can save the day when your office blasts the AC to arctic levels, temperatures drop in the evening, or while traveling (airplanes are significantly cooler than I always expect).
