A tan cardigan and chinos are the kind of casual staples that you can wear for years to come. If you want to break out of the mold a little, add a pair of white canvas low top sneakers to your getup. As you can see, this ensemble is a really smart option, especially for awkward fall weather, when the temperatures are dropping. Wondering how to master casual looks as you move through your teen years? This pairing is a wonderful example.
