Whether they’re jetting off to a tropical paradise or braving the Chicago freeze, partygoers know that blue is the coolest color for any temp. Flattering on any skin tone, the watery hue is having its time in the sun this season. Jazz it up with sequins or lace, or keep it ultra-refined with elegant gathering. Whatever you choose, break out the accessories — belts, bags and bling are all fair game. A chic cerulean gown is the perfect choice for this month’s galas, but a sleek, above-the-knee cut is a must-pack for any stylish getaway. It’s the perfect antidote to the winter blues.
