This off-duty combo of a light blue crew-neck t-shirt and white chinos is a fail-safe option when you need to look nice in a flash. We adore how complete this outfit looks when rounded off with a pair of white canvas low top sneakers. As we all know, the key to getting through the hottest time of year is dressing in cool outfits like this one. This is an amazing example of how to look stylish during your teenage years.
