"Forget the age-old notion that white nail polish is mutually exclusive with summer — in fact, I personally think it makes an even better hue come winter. Not only will it match the crisp snow that tends to fall this season, but it also pops against your fingerless gloves and heavier jackets. My favourite of late is the Sundays No.01: Pure White ($18), which can be worn alone or as the perfect base to a minimalistic nail-art look." — Kelsey Castañon, beauty director
