One annual tip-off that winter is ~officially~ here? Swapping the bright shades, French manicures, and nude nails we’ve had in rotation for winter nail polish colors that feel more in line with sweater weather. We’re talking nail colors that look good peeking out of an oversized knit or under a sparkly clutch—or, let's be real, with the beloved sweats we still can't quit. Think of them as the mani equivalent of the first play of Mariah Carey's “All I Want for Christmas Is You”; the joy they bring is impossible to resist even if they're hidden under gloves when you're actually out and about.
