Obviously mid Polar Vortex, we don’t have to tell you why your chunky knits are absolutely non-negotiable. If you’re battling arctic conditions, layering is practically a religion, and you’re one devoted sartorial saint. But once the sun shows its face again and blue skies are on the horizon, once festival season is just around the corner, you may be tempted to pack away those knits. Think again. Sunny spring days turn to chilly nights and that spring breeze drops the temperature lower than you’d like. Cue the transitional knits. These cozy staples will take you from snowstorms to snow thaws straight onto spring. Trust.
