Pairing a blazer with a white long sleeve shirt is an awesome choice for an effortlessly smart ensemble. When it comes to shoes, go for something on the classier end of the spectrum by wearing a pair of black leather loafers. It's a great idea if you're putting together a well-coordinated outfit for summer-to-fall weather. As you're progressing through your teen years, you probably want to look older than your age. If that's the case, getups like this become very relevant.
