Functional Fashion Tip: It’s winter, and your hands are freezing. Full-on mittens or gloves are too bulky for wrangling your stopwatch or iPod, and maybe even too hot after running a few blocks. What to do? Iris swears by these cashmere fingerless gloves. Cashmere generates enough heat for your whole hand, even with the gadget-friendly open fingers, and it’s light and thin, so you’ll forget you’re even wearing gloves. BONUS: If your fingers freeze at the computer keyboard, these gloves keep your hands toasty while still letting you type.
