When the setting allows a casual look, go for a turtleneck and blue overalls. If you want to easily play down this ensemble with footwear, why not complement your getup with a pair of black and white canvas high top sneakers? When you're having one of those bleak autumn days, sometimes only a knockout look like this one can get you to face the outside world. On the lookout for outfit ideas for teenage guys? This combination is pretty inspiring.
