Photo: Alison Freer One cold February day in California, I was on a film set high above Malibu when it began to snow. Everyone started laughing, taking selfies, and shivering, except for the great Tracey Levy: makeup artist to the stars, impossibly chic human, and mom of author Honor Levy. She simply pulled this sleek, insulated snow skirt by Swedish brand Skhoop from her tote bag, slipped it on over her pants, and warmly went about her day.
