Consider wearing a teal overcoat and a turtleneck for casual elegance with a rugged finish. When it comes to shoes, go for something on the laid-back end of the spectrum and complete your look with a pair of white athletic shoes. Surely a popular option if we're talking fashion for adolescent guys.
For an ensemble that's effortlessly sleek and GQ-worthy, try teaming a teal overcoat with a turtleneck. Hesitant about how to finish? Introduce a pair of dark green suede desert boots to the mix to mix things up a bit. If you want people to see maturity in you as a teen, an outfit like this is a solid bet.
