A yellow puffer jacket and blue jeans are a combo that every modern girl should have in her casual arsenal. Introduce a touch of casualness to this look by finishing off with black suede lace-up flat boots. During the winter season, when warmth is the priority, it can be easy to surrender to a less-than-stylish outfit in the name of practicality. This outfit, however, is a shining example that you can actually stay toasty and remain equally stylish during the winter season.
