A navy long sleeve shirt and a crew-neck t-shirt are a great look to add to your current casual rotation. If you feel like dressing up a bit now, complement this getup with black leather chelsea boots. When it's one of those gloomy autumn days, sometimes only a knockout getup like this one can brighten it up. As you're maturing from a kid to a teen, you probably want to look older. If that's the case, getups like this come in handy.
