Marrying a beige shawl cardigan with a light blue chambray dress shirt is an awesome choice for a classic and sophisticated ensemble. Break up this ensemble with a classier kind of footwear, such as this pair of tobacco leather double monks. As you can see here, this outfit is a really nice choice, especially for transeasonal weather, when the temperature is dropping. So if you're on a mission for outfit ideas on how to dress in your 20s, this ensemble is definitely worth saving for later.
