A blue blazer and khaki chinos are the kind of a no-brainer look that you need when you have zero time to pull together an outfit. Slip into a pair of high top sneakers to avoid looking too polished. It's a viable pick if you're crafting a well-coordinated ensemble for awkward fall weather. So if you're scouting for style ideas on how to dress as you work your way through your adolescence, this ensemble is definitely worth saving for later.
