Depending on where you live, this lion/lamb/cruelest-month time period is unbelievably frustrating. You’re 150 percent ready to wear the voiles and toiles and floral prints and “Color!” the magazines have been screaming about for months, but every day the black tights, gray sweater and boots that need resoling triumph anew. Here is my $10, two-second total solution: the striped or floral-print Sally Hansen peel-off nail polish, for hands or feet. Insta-spring! Insta-fashion! And you insta-get to wear it: There’s no drying time, so you can slip the boots that need resoling right back on and clomp away through the frozen sludge. (The more weather-fortunate can slip on their new ripped-silk Lanvin sandals and step away daintily through the primroses.)
