Demonstrate that you do off-duty like a fashion pro by wearing a cable sweater and a long sleeve shirt. To add a little flair to this getup, go for a pair of beige suede derby shoes. During the colder months, when warmth is everything, it can be easy to settle for a less-than-stylish getup. This getup, however, is a good illustration that you can actually stay toasty and remain stylish during the colder months. Wondering how to master classic and casual outfits as you go through your adolescence? This combination is the perfect answer.
