Putting together a white and blue dress shirt with beige dress pants is a savvy idea for a stylish and sophisticated getup. Dial down the formality of this look by finishing off with a pair of athletic shoes. During the winter months, when practicality is the priority, it can be easy to settle for a less-than-stylish outfit in the name of functionality. However, this outfit proves that you totally can stay toasty and remain stylish in the winter months. Sleeker outfits like this look well on 30-somethings.
